Understanding Wear and Friction To capitalize on the benefits of thermoplastic compounds, it is helpful to understand the basics of wear and friction. Most engineers who are concerned with friction and wear performance compare tribological parameters to judge the suitability of a compound for an application. Tribological parameters include: wear factor (K) static coefficient of friction (µ S ) dynamic coefficient of friction (µ K ) pressure-velocity (PV) RTP Company is committed to continuous research and development, allowing us to stay on the cutting edge of wear technology. Our wear testing lab allows us to do long term wear resistant testing to compare the performance of materials. This guide provides the data obtained in our lab to assist in comparison and selection of the best product for your application. WHAT IS TRIBOLOGY? Tribology is an engineering discipline that incorporates design, friction, wear, and lubrication of interacting surfaces in relative motion. Materials selected for wear resistant applications need to have an acceptable combination of mechanical and tribological properties. Tribological applications commonly include: Bearings Bushings Gears Piston Heads Pulleys Rollers Seals Syringes www.rtpcompany.com 3
In combination with selecting the best resin for an application, RTP Company uses a variety of wear and friction additives. Each type of additive has special characteristics that will make it a prime candidate for a specific application. Our engineers also combine these additives in just the right formulation to provide you with a custom compounded solution. Wear Resistant Additives Polytetrafluoroethylene (PTFE) Typical Loadings: 5-20% Powdered PTFE is a workhorse additive for wear resistant materials providing the lowest coefficient of friction of internal lubricants. PTFE forms a lubricious film on the surface and modifies the mating surface after a break-in period. PTFE facilitates higher dynamic load bearing capability. Molybdenum Disulfide (MoS 2 ) Typical Loadings: 1-5% A fine gray powder that best functions as a wear additive in nylon/metal wear combinations. It works by nucleating and forming a hard nylon wear surface and by smoothing the sharp and abrasive microscopic pores of the metal. Fibers Glass, carbon, and aramid fibers provide the necessary integrity for a compound to survive in more demanding applications. Each type of fiber has exclusive benefits. For example, aramid fibers are known to be soft and non-abrasive to the mating surface. Graphite Powder Typical Loadings: 5-30% A soft black carbon material whose unique chemical lattice structure allow the molecules to slide easily over one another, providing lubricating qualities. 4 www.rtpcompany.com
The diagram illustrates the frequency of usage of different wear and friction additives by RTP Company. The most common wear additive in the industry is PTFE and also PTFE in combination with silicone. Additionally, glass fibers are commonly used with these additives for mechanical strength improvement, and sometimes increased wear resistance. Polydimethylsiloxane (Silicone) Typical Loadings: 1-3% Acts as a boundary lubricant because it migrates to the surface over time. This migration reduces start-up wear and friction and is ideal for low pressure and high speed applications. Perfluoropolyether (PFPE) Typical Loadings: <1% A synthetic oil with loading levels of <1% provides benefits such as: minimized die plate-out, lower specific gravity, and maintained physical properties. www.rtpcompany.com 5
Testing Capabilities RTP Company has the capability to perform the following tests at our global headquarters in Winona, MN ASTM D-3702: Thrust Washer Wear Test The most common test for evaluating the wear performance and the dynamic coefficient of friction of thermoplastics and thermoplastic compounds. Six machines are constantly spinning at RTP Company in our wear testing lab Used to quantify the volumetric loss of material, or wear factor (K), which is used to numerically compare materials to each other. The data in this guide is obtained from this test. ASTM D-1894: Static and Dynamic Coefficient of Friction Sled Test Used to determine the static and dynamic coefficient of friction Data from this test is not contained in this guide. Please contact RTP Company for more information on utilizing this test. 6 www.rtpcompany.com
This test is used to provide a quantitative measurement of sliding wear resistance. This value is referred to as the wear factor (K) and is an indication of a materials resistance to wear as a function of the volume of material lost, force (load) and velocity at the wear interface and time. Sample discs are molded or machined according to the standard and are attached to the rotating spindle head. A contact surface (thrust washer) is selected and will remain stationary as the sample rotates on its surface under a set load/pressure (P) and velocity (V). Testing at different PV conditions will help determine the wear resistant capabilities and limitations of a material. Once the test is completed the volumetric loss of material is calculated by converting the total mass loss of the sample into the wear volume (W). Dividing W by the product of the force (F), velocity (V), and elapsed time (T) of the test will yield the Wear Factor (K). The resulting wear factor is used to compare the wear resistance of materials to each other. A low value for K indicates a better resistance to sliding wear. This guide will compare the wear factors of a variety of RTP Company materials. The dynamic coefficient of friction is also determined from this test and can be used to help a material selection process. Comparing Competitive Data Note: RTP Company reports wear factors per unit force (K F ) with units of (in 3 min/ft lb hr)10-10. This is the industry standard way to calculate and report wear factor. Some suppliers report wear factors per unit Pressure (K P ) with units of (in 5 min/ft lb hr)10-10. This value is arrived at by multiplying K F by (0.35 in 2 ). As a result of not using the industry standard calculations, some competitors wear factors appear artificially low. For example a K F of 9 (in 3 min/ft lb hr)10-10 would be equal to K P of 9*0.35 in 2 = 3.15 (in 5 min/ft lb hr)10-10. www.rtpcompany.com 7
Abrasive Wear When harder surfaces scrape or abrade away the mating part. A type of wear characterized by grooves or gouges cut into a parts surface. If wear particles are hard and abrasive, they will roll between surfaces and scratch the counter surface, causing severe abrasion. Adhesive Wear Occurs with two surfaces sliding against each other. The primary wear result for thermoplastics, characterized by transfer of material to a mating surface sufficient to inhibit sliding at the original interface. PTFE, a common additive in compounds, effectively transfers a film to smooth the mating surfaces and reduces wear. Break-in Period A 1500 min pre-test for ASTM D-3702 to allow the surface to become flat and obtain an intimate contact with its counter surface. This can also allow for a lubricious layer to form between the surfaces as well. Dynamic Coefficient of Friction Ratio of the force required to sustain constant motion between two contacting bodies and the force pressing them together. Hydrodynamic Film Lubricious and often fluid film that forms on the contact surfaces of two materials. This allows the surfaces to glide over the film and minimize the amount of contact between them. Limiting PV A value (a PV condition, ex. 10,000 PV) that is the maximum condition a material can perform at without failing. Pressure Velocity Condition Product of pressure and velocity of a given wear and friction test. Referred to as PV, this value compares severity of a test condition. A lower PV indicates a low load and velocity during a test, while a high PV indicates a demanding test. Static Coefficient of Friction Ratio of the force required to initiate motion between two contacting bodies and the force pressing them together. Stick-Slip Phenomenon Occurs when the dynamic coefficient of friction is greater than the static coefficient of friction. The relative motion of surfaces will rapidly start and stop, causing a squeaking sound. This is seen when the difference between static and dynamic coefficient of friction is high. Tribology Science of the mechanisms of friction, lubrication, and wear of interacting surfaces that are in relative motion. Wear Gradual material loss caused by a contacting object over time. Wear Factor Wear factor (K) is the volumetric loss of material over time at a given pressure (P) and velocity (V). This value is used to compare wear resistance performance of materials to each other. Wear Limit Wear limit (WL) is when a sample fails (breaks, wears out, melts, etc.) before the end of a test. 8 www.rtpcompany.com
