Under brush plating the behaviour of the electrodeposition of metal titanium and the prescriptions of brush plating solution contaning titanium have been studied systematically in this paper. Based on this study, the four kinds of the prescriptions A,B,C and D are put forward. The properties of both coats for the solution A and B have been determined all-sidely. The result shows A and B both meet the stipulated technical requirements and have the following advantages :1. Their hardness can basically keep constant within 500℃ and increase slightly, which displays clear superiority to that of the brush plating solution High-speed Nickel, Nickel-Tungsten D used widely in China.2. Their corrosion resistance is good. The soaking test in 30% NaOH, 20% H;SO;, man-made seawater and organic acid atmosphere test show their corrosion resistance is fairly good; besides, salt spray test is OK. The concerned factories have been interested in those good properties and begun to use them. We consider that both coats containing titanium may replace stainless steel and some noble metals, Based on microstructure analyses for the above coats, we confirm that some amorphous solid exists in both coats containing titanium, and the crystallizing temperature is between 500～550℃.
