Differences in performance between cyanide free cadmium titanium plating and cyanide plated cadmium titanium plating on different steel surfaces
Cyanide free cadmium titanium plating and cyanide cadmium titanium plating were per-formed on the surfaces of different steel substrates, and the hydrogen embrittlement, fatigue, and ten-sile properties of the coatings were compared between the two processes on the surfaces of different steel substrates. The results show that there is no significant difference in hydrogen embrittlement perfor-mance between 300M steel and 4340 steel after cyanide free cadmium titanium plating and cyanide plat-ed cadmium titanium plating. After cyanide free cadmium titanium plating and cyanide plated cadmium titanium plating on 300M steel and 50CrVA steel, there was a small change in fatigue performance. Af-ter cyanide free cadmium titanium plating on 50CrVA steel, the fatigue limit was reduced by 1.5％ com-pared to the bare material, and after cyanide plating on cadmium titanium, the fatigue limit was in-creased by 5.0％ compared to the bare material. After cyanide free cadmium titanium plating at 300M steel, the fatigue limit increased by 3％ compared to the bare material. After cyanide plating cadmium ti-tanium, the fatigue limit was reduced by 7％ compared to bare materials. Cyanide free electroplating of cadmium titanium has little effect on the tensile properties of 300M steel and 50CrVA steel matrices, and compared to bare materials, the fluctuation of various index values is within 5％.
