Regarding phosphating treatment
Thread Content
Dear all**, may I ask what the main raw materials used for phosphating treatment are, and what the optimal temperature for this treatment is?
I have phosphorus acid, oxyphosphorus, and triethyl phosphate here, but I’m not sure about your question
The main component of the phosphating solution is dihydrogen phosphate, that is, H2PO4; it has a valence of 2. Depending on the requirements, the cation used in the phosphating solution can be chosen arbitrarily – for example, zinc salt phosphating, zinc-calcium salt phosphating, iron salt phosphating, manganese salt phosphating, etc~~
I’m mainly doing a layer of protective coating for the WCB parts
Then, if the main body is made of WCB material, which type should be used?
Cast iron can be phosphated using zinc salts or iron salts~
No, this is made of cast steel, cast carbon steel
I made a mistake; it should be cast steel~~
