利用冶金新技术在工件表面涂覆ＦＮＡ涂层能改变基材和工作表面的成分及组织，从而满足所需要的理化性能。Ｎｉ－Ｃｒ－Ｂ－Ｓｉ系列之一的ＰＳＲ－１涂层是理化性能良好的合金层，而合理熔烧工艺的实施是保证涂层质量的关键。
The use of new metallurgical technology in the workpiece surface coating FNA coating can change the composition and organization of the substrate and the work surface to meet the needs of the physical and chemical properties. The PSR-1 coating, one of the Ni-Cr-B-Si series, is an alloy layer with good physical and chemical properties. The proper melting process is the key to ensure the coating quality.
