首次研究了钨和碳双注入对抗磨损和抗腐蚀特性的影响,研究了抗磨损和抗腐蚀相生成的条件,以及这些相对抗磨损和抗腐蚀特性的作用,并对其改性机理进行了讨论.实验结果表明,钨和碳双注入H13钢可在注入层中形成超饱和的钨和碳原子浓度.因此在注入层中形成钨的碳化物wC和w2C相、合金相Fe2W和Fe2w6C等,这些弥散相不但可以使注入层强化,而且也可增强表面磨损和抗腐蚀特性;钨和碳双注入具有钨和碳单注入的特性,所以能进一步地提高H13钢的抗腐蚀性,随着w和C注入剂量的增加,抗磨损和抗腐蚀特性进一步提高;抗磨损特性可改善2倍.双注入样品抗腐蚀特性也有明显地提高,如样品w5C8的腐蚀电流峰值密度Jp经55个周期腐蚀后,其值是H13钢Jp的1/26.7~1/33.3,而钨样品C5W5经过88个周期腐蚀后,其值是H13钢的1/16~1/20.
