Can alloy products be vacuum plated

Summary of reasons why alloys are not suitable for vacuum plating in vacuum furnaces:
1. Because the alloy object is not resistant to high temperature (usually the temperature in the vacuum furnace is as high as 200 ° C), the alloy vacuum plating starts to foam after 110 ° C; affecting the appearance of the product;
2. When the alloy object is vacuum-coated, the bottom layer needs to be hit in the early stage, which invisibly increases the complexity of the process;
3. Compared with stainless steel, titanium steel or other pure metal plating parts, the cost of vacuum plating of alloy objects is relatively high;
