Co-Cr-W-C合金是一种用途广泛的耐磨合金。它不仅具有较高的强度、硬度和优良的耐磨、耐蚀性能,而且红硬性也很好。由于该合金的Cr、W及C含量都较高,所以变形十分困难。长期以来它主要用来在零件表面进行堆焊,起到耐磨耐蚀作用,使用状态基本上是铸态组织。随着使用领域的不断扩大,对合金性能的要求也越来越高。在一些条件苛刻的工作环境 Co-Cr-W-C alloy is a versatile wear-resistant alloy. It not only has high strength, hardness and excellent wear resistance, corrosion resistance, but also red hardness is also very good. As the alloy Cr, W and C are high, so the deformation is very difficult. For a long time it is mainly used for surfacing the part surface, play a role in wear and corrosion resistance, the use of the state is basically as-cast structure. With the continuous expansion of the field of use, the performance requirements of the alloy are also getting higher and higher. In some harsh working conditions
