补充资料：高耐磨的碳化钨注渗钢基合金在塑料机械中的应用
碳化钨注渗钢基合金（下简称WCSA）技术，又名碳化钨——钢梯度耐磨材料制造技术。该技术已获得国家发明专利，具有自主知识产权。WCSA是采用高能离子注渗技术，在钢铁零部件表层内注渗进高耐磨的碳化钨（下简称WC），WC注渗层深度1.2-1.5mm，其中WC含量较多的富集层达到0.3-0.5mm。零部件表层获得WC“盔甲”后,硬度高，强韧性好,抗磨性能更好。WCSA应用于各种塑料机械中，使用寿命比目前塑料机械中常用的离子氮化层、堆焊或喷涂耐磨层、高合金工具钢、高速钢和不锈钢等材料制造成的零部件的使用寿命提高3-8倍，深受塑料机械制造商和塑料制品生产商的青睐。
