摘　　要：利用氯基熔盐在正常大气压下,对钢表面进行被覆TiC处理,可以得到高硬度、高耐磨性、高耐蚀性的TiC被覆层。研究表明,钢中含碳量及碳的存在形式对被覆层的形成过程有重要影响。通过对含碳量不同的钢种进行被覆处理,确定了在氯基熔盐被覆处理条件下,钢中所需的最低含碳量。High hardness, good wear resistance and corrosion resistance can be acquired simultaneously by coating TiC in chloridebased baths on the steel surface under ambient atmosphere. It is found that the content and form of carbon in steel both affect the formation of the coating. The lowest carbon content in steel suitable for the process is determined by coating steel samples with different carbon contents and by assessment of the quality of the coating.
