摘要热反应沉积（TRD）在金属热处理技术的范畴内，即在熔融盐浴和来自粉末包装箱和流化床的气体中产生致密的碳化物和氮化物涂层。碳和氮从涂层基材的热扩散导致厚涂层，确保在涂层和基材之间形成非常高强度的冶金结合。该工艺自20世纪70年代早期以来一直在使用，因为它具有优于化学气相沉积和物理气相沉积的许多优点，包括上级性能和低投资成本等。
Abstract Thermo-reactive deposition (TRD) produces dense coatings of carbides and nitrides within the category of heat treating technology of metals, namely in molten salt baths and in gases from powder packing boxes and fluidizing beds. Thermal diffusion of carbon and nitrogen from the coated substrates results in thick coatings, ensuring that very high strength metallurgical bonds form between coating and substrate. The process has been used since the early 1970s, because it has a number of advantages over chemical vapor deposition and physical vapor deposition, including superior performance, and low investment cost, among others.
