一种TiB2金属陶瓷耐磨涂层的制备方法
摘要：
本发明提供一种高韧高耐磨TiB2金属陶瓷涂层的制备方法，采用TIG弧熔化包含TiB2的前驱物及Cr、Ni、Mn、Si合金的粉芯丝材，利用TiB2在熔池中原位合成，形成金属与TiB2结合致密的TiB2金属陶瓷涂层。所获得的涂层中TiB2体积百分含量达到15％～60％，涂层硬度HB380～780。
摘要（英）：

The invention provides a method for preparing a high-tenacity high-wear-resistance TiB2 metal ceramic coating. The method comprises the following steps of: melting a TiB2-containing precursor and a powder cored wire made of a Cr, Ni, Mn and Si alloy by using a tungsten inert gas (TIG) arc; and performing in-situ combination in a molten pool by using TiB2 to form the TiB2 metal ceramic coating on which metal is compactly combined with the TiB2, wherein the TiB2 accounts for 15 to 60 percent of the volume of the obtained coating, and the hardness HB of the coating is 380 to 780.
