2 Technology ARCOR - CARBONITROOXIDACE surface treatment developed to provide a multipurpose surface properties these properties increase resistance to wear, galling and fatigue corrosion resistance (in excess of 600 hours by neutral salt spray test) surface treatment meet the increasingly challenging operating conditions required mechanical components made of steel, cast iron and alloy steel The finish is founded on carbonitrooxidation, followed by various other adjustments provides efficient, economical solutions to meet the environmental regulations The most modern technology solutions through CLIN (Controlled Liquid Ionic Nitriding) It is driven liquid ionic nitriding developed by a group HEF It provides real optimizing the required parameters.

3 Technology ARCOR is used in: in the automotive industry in the arms industry in the aviation industry and aviation manufacturing hydraulic in the production of hydraulic machine and agricultural machinery in the production of of pumps and chemical equipment in the production of metalworking and woodworking machines in the production of textile and sewing machines in the production of optical devices Multifunctional properties : high mechanical properties good frictional properties high corrosion resistance functionality roughness obtaining an effect of surface appearance

4 I. Technical description ARCOR = technology Carbo-Nitro-oxidation, which is carried in the melt of alkalic metal salts at a temperature C ± 5 C, followed oxidation. The process Carbo-Nitro-oxidation is very progressive and is used for the purpose of: Fe material processing hardening of the material surface obtaining high toughness of the material friction material - wear problems galling material corrosion resistance effective appearance matt black, glossy finish. Industrial applications: gears, shafts, rollers and mechanical components, axis, centrifugal clutch finishing matrices, tools, molds for plastic injection Al, replacement for hard chrome, valves of combustion engines,crankshaft and camshafts, the wiper shaft, worm shaft, gear shaft and sprocket gears, ball joints, hydraulic systems, piston rod, rod dampers, flanges, pumps, gate valves, guide rods, gear boxes, valve bodies, the set screws, fasteners, timing gears, automotive locks, etc.

5 ARCOR =SURSULF+ OXYNIT The technology is a combination ARCOR carbonitridace in salt bath sursulf operating at a temperature T = ± 5 C and oxidation in salt bath OXYNIT temperature 430 ± 15 C. ARCOR technology is used to solve problems galling / adhesion, wear / abrasion, fatigue and corrosion. Carbonitrooxidace = Nitrocarborace The special composition of the salt bath SURSULF ensures very high nitriding potential Consequently, that: - the compounds of salt/ Li +, K +, Na +, CNO-, CO3 - ensuring better chemical and thermal stability bath - increased the kinetics of diffusion of nitrogen into Fe materiál Supports the creation of a homogeneous layer of nitride and allows you to create a structure and thickness layers so as to be able to give a solution and the results of such problems, such as wear, galling, corrosion and fatigue.

6 Technology ARCOR is in its application very reliable, is reproducible at all Fe materials under very exceptional properties that this modified products and components will obtained. These features are further improved by low operating costs so modified components and products. Technology SURSULF = carbonitriding bath was developed by French company H.E.F. : Is low polluting for the enviroment bath allows, depending on the regulation of function parameters, various types micro layers starting from the compact layers of different thickness to the porous layer. Bath allows to obtain a micro layer well adapted to the desired problem of wear, galling, corrosion and gives the machined parts brought exceptional fatigue resistance and effective black finish.

7 II. Technical specification and parameters Standard technology ARCOR 1. Degreasing C (depending on the product type) 2. Rinse with warm water C 3. Preheating C 4. Technology SURSULF ± 5 C / Technology time is variable depending on the desired purpose and type of iron alloys from 30 'to 240' minutes 5. Technology OXYNIT 430 ± 15 C, time = Water cooling by immersion 7. Rinse with warm water C 8. Conditioning and drying To obtain a glossy black surface it is necessary to include again tumbling and components undergo technology Oxynit. The parts will reach the desired gloss, roughness / Ra = such as before the surface treatment and corrosion resistant surface.

8 Description layers SURSULF is substantially nitriding technology and it follows morphology of the layer and its thickness, its mechanical properties, the penetration of nitrogen into the base, and this varies depending on the nature of the base, especially in its chemical composition, the content of chromium, molybdenum, nickel, etc.. The following describes an example layer SURSULF obtained on non-alloy steel XC 38 Annealed and processed for 90 minutes in a bath containing about 37% of the cyanate. If we execute micrographic cut, we can say that the technology of steel from outside towards the inside of the part: Surface layer entitled "COMBINATION LAYER," which is produced especially the iron nitride Fe2-3N, where is gentle scatter on the outside(porosity) of sulfur particles and salt bath. The total thickness this layer combination is: - 10 to 14 microns, of which on the outside 2-4 micron fine porosity baths with a low content of sulfur particles - 15 to 20 microns, of which on the outside microns fine porosity baths rich sulfur particles Medium hardness of the combination layer in this point is approximately 800 Hv 0,025. Zone called "diffusion layer" with decreasing concentration of nitrogen to the extent as it penetrates into the base, with a thickness which can reach 0.5 to 0.7 mm with a progressively increasing hardness of about Hv01. Under the combination layer with approximately Hv 01 at a depth 0.3 mm for the core hardness approximately Hv01. Hardness identified crosssection.

9 Operating parameter In addition to the chemistry of bath, referred to in the previous section. They condition three parameters creation a good result SURSULF technology: 1. bath temperature 2. quantity, homogenity bath 3. air circulation in the bath.
