10 CB-CERATIZIT Production Sites 09 Innovative R&D Team In order to solve the corrosion problem of cemented carbide, CB CERATIZIT experts collaborated with branded WEDM machine manufacturers to create the new corrosion resistant carbide grades NF series, Corrosion resistance concept works in the beginning of grade preparation by mixing the powder with corrosion inhibitor elements. Once the NF grade carbide contacts with dielectric substance (e.g. water, lubricant etc.), a thin layer of oxide will form on the surface of the carbide for protection. It will isolate the carbide with the outside environment and thus preventing it from further corrosion, the protection is sustainable, and continuous throughout the whole machining processing. The NF series corrosion free grade has the below advantages: 1.) Able to sustain in more extreme dielectric medium condition in the WEDM process, thus help to eliminate corrosion factor due to poor filtration and also help to cut down filtration cost. 2.) Reduce extra prevention measure to avoid carbide corrosion which may affect the quality of work pieces and therefore save cost. 3.) Maintain a good surface quality after machining, improve tool life. Hardness / Wear Resistance The mechanical property of carbide can be altered by changing grain size and constitute to cope with wide range of tool performance demand. Consequently, features of CB-CERATIZIT grade can also be modified in accordance with different machining methodology. CB-CERATIZIT can offer best-fit solutions for special work piece metals such as harden material with high wear resistance, Nicochrome which can withstand high temperature, and Composite material with complicated mechanical properties.

14 Grade Property & Recoendation Concept of NF Corrosion Free Grade 13 Corrosion is still a topic which must be taken seriously. While in the past years corrosion was mainly associated with wire erosion, today s increasing demands mean that follow-up processes like further machining operations and handling are now also becoming more and more important. Severe wear in active components is frequently due to corrosive damage.

It is therefore necessary to speak the same language with regard to the dimensions indicated in the drawings in order to manufacture products correctly (see illustrations below). In this context, it is a big advantage for you that you can illustrate the hole specifications etc. in a simplified way. The part will then be supplied in accordance with the appropriate tables. The way of transmitting the drawing represents a significant factor with regard to the time taken to process an order and the quality that is achieved. This is why we are going to use drawing transmission via to a larger degree. The file format should be.dwg or.dxf and large data amounts should be zipped.

22 Technical Information Mechanical Property 29 Hardness HV Hardness Hardness is a material's mechanical resistance to another, harder, material which penetrates it. This value is usually measured by "Vickers Harndess Procedure" (ISO 3878) or "Rockwell Hardness Procedure" (ISO 3738). Like wear resistance, hardness also increases with a smaller grain size and lower cobalt content. Therefore, hardness is often used as a reference for wear resistance. Ultrafine grades Submicron grades Fine / Medium grades Coarse grades Figure 1: Hardness in relation to the cobalt content and grain size Transverse rupture strength [MPa] Cobalt content [%] Cobalt content [%] Transverse Rupture Strength Testing "Transverse Rupture Strength" is a coon procedure to analyse the mechanical property of carbide. Based on ISO 3327 standard, a material with fixed length is placed on two contact points and certain stress is given in the milddle until the material breaks. The average value of several tests is then determined as T.R.S. (Transverse Rupture Strength) Ultrafine grades Submicron grades Fine / Medium grades Coarse grades Figure 2: Transverse rupture strength in relation to the grain size and thecobalt content Technical Information Mechanical Property Toughness K IC [MN/m 3/2 ] Fracture Toughness When a material is exposed to external stress, this leads to mechanical tensions. Under this circumstances, both the strengh and ductility of the material indicate the basis for the concept of toughness. In other words, toughness is defined as the capacity to resist fracture or rupture growth. "Palmqvist Method" is frequently applied to determine the toughness value, KIC Cobalt content [%] Ultrafine grades Submicron grades Fine / Medium grades Coarse grain grades Figure 3: Fracture toughness in relation to the grain size and the cobalt content

23 30 Technical Information Mechanical Property Compressive strength [N/ 2 ] Cobalt content [%] Compressive Strength One of the most remarkable properties of carbide is the extremely high compressive strengh under uniaxial stress. This precious property is applied to almost all applications. When metal binder content decreases and the grain size decreases, the compressive strength increases. A small grain carbide with a low metal binder content typically has a compressive strength of almost 7,000 N/2. The compressive strength decreases when the temperature increases. The degree of plastic deformation increase notably with the temperature, so that the results are variable when temperatures are high. Technical Information Mechanical Property Thermal conductivity [W/m*n C] Temperature [ C] Submicron grades Fine / Medium grades Thermal Conductivity Coarse grades Extra-coarse grades Figure 4: Compressive strength in relation to the grain size and the cobalt content The thermal conductivity plays an important role in carbide applications, it determines the temperature in the wear areas and has a large influence on the carbide's thermal fatigure resistance and resistance to thermal fluctuations. The thermal conductivity of carbide is around twice as high as that of non-alloyed steel. Submicron grades Fine / Medium grades High y-phase content Coarse grades Low y-phase content Figure 5: Thermal conductivity in relation to the temperature of various micro-structures and grain sizes

24 Technical Information Mechanical Property 31 Modulus of elasticity [kn/ 2 ] Cobalt content[%] Modulus of Elasticity The modulus of elasticity indicates the resistance of a material against elastic deformation. The modulus of elasticity for carbide is 2 to 3 times higher than in steel. It will increase linearly with decreaseing metal binder content. Figure 6: Modulus of elasticity of WC-Co carbides B R B -H C H S H Magnetic Saturation Carbides with cobalt as a metal binder are ferromagnetic. If a ferromagnetic material is exposed to a magnetic field strength H, the magnetic flux density B in this material increases (blue line). The flux density decreases when the field strength rises, until maximum saturation is achieved. Coercive Force Coercive Force is one of the property of magnetic material. The inverse field strength HC which is necessary to reduce the magnetic flux density to zero, or to 'de-magnetise' the material, is defined as coercive force. Coercive Force is usually measured in oersted (Oe) or ampere/meter (A/m) units and is denoted HC. It can be measured using a B-H analyzer or magnetometer.
