在这项工作中，硬化，tuffritized和碳化铬涂层AISI 52100钢球对硬化和碳化铬涂层AISI D2钢盘的摩擦学行为进行了研究，在1，2和5 N的负载。碳化铬涂层采用包裹法。在该方法中，AISI 52100钢样品被涂覆在由铬铁、氯化铵和氧化铝组成的粉末混合物中。在商业盐浴中进行凝灰化处理。磨损试验采用球盘结构系统进行。测试条件包括0.125 m/s速度和1、2和5 N载荷。硬化、软氮化和碳化铬涂层球与硬化AISI D2钢盘的磨损率分别在1.8×10−6-7.7×10−6、4.7×10−7-2.5×10− 6和1.3×10−7-1.0×10− 6 mm 3/m之间变化。硬化、软氮化和碳化铬涂层球与碳化铬涂层AISI D2钢盘的磨损率分别在3.1×10−6-8.0×10−6、2.0×10−6-5.9×10− 6和1.8×10−7-4.3×10− 7 mm 3/m之间变化。此外，涂层和未涂层钢的磨损率显示出对反盘施加的载荷更敏感。
In this work, the tribological behavior of hardened, tufftrited and chromium carbide coated AISI 52100 steel balls against hardened and chromium carbide coated AISI D2 steel discs have been studied under 1, 2 and 5 N loads. Chromium carbide coating was performed by pack method. In this method, AISI 52100 steel sample was coated in the powder mixture consisting of ferro-chromium, ammonium chloride and alumina. Tufftriting treatment was performed in the commercial salt bath. The wear test was carried out with ball-on-disc configuration system. Test conditions covered 0.125 m/s speed and 1, 2 and 5 N loads. The wear rate of hardened, tufftrited and chromium carbide coated balls versus hardened AISI D2 steel disc were changing between 1.8×10−6–7.7×10−6, 4.7×10−7–2.5×10−6and 1.3×10−7–1.0×10−6mm3/m, respectively. The wear rate of hardened, tufftrited and chromium carbide coated balls versus chromium carbide coated AISI D2 steel disc were changing between 3.1×10−6–8.0×10−6, 2.0×10−6–5.9×10−6and 1.8×10−7–4.3×10−7mm3/m, respectively. Moreover, the wear rates of coated and uncoated steel showed more sensitivity to the applied load against the counter discs.
