本工作曾分别在典型冷作模具材料 T10A、Cr12钢表面化学沉积非晶钴磷和钴钨磷镀层,并用 X 射线衍射。经显微硬度和磨损试验研究,测定了镀层及其在晶化过程中的结构和性能,试验表明,镀层在晶化过程中析出的金属微晶相和高硬度弥散的磷化物相使镀层硬度、耐磨性提高,在一定温度下达到峰值。化学沉积层使表面得到高硬度、高耐磨性的同时,心部保持足够的韧性。因此,应用于冷作模具可提高模具质量和使用寿命。用于形状复杂模具,可避免常规热处理产生的变形。 This work has been in the typical cold-working die material T10A, Cr12 steel surface chemical deposition of amorphous cobalt and cobalt tungsten tungsten phosphorus coating, and X-ray diffraction. The microhardness and wear test study, the coating and its structure and properties in the crystallization process was measured, the test shows that the coating in the crystallization process precipitated metal microcrystalline phase and high hardness dispersed phosphide phase coating hardness , Wear resistance increased at a certain temperature peak. Chemical deposition layer so that the surface of high hardness, high wear resistance at the same time, the Ministry of the heart to maintain adequate toughness. Therefore, applied to cold work die can improve mold quality and service life. For complex shape mold, to avoid the deformation caused by conventional heat treatment.
