Heat-resistant electroplating solution

Abstract

The invention discloses a heat-resistant electroplating solution which comprises components of raw materials in parts as follows: 50-60 parts of ammonium molybdate, 40-45 parts of ammonium ferrous sulfate, 35-45 parts of antimony potassium tartrate, 10-15 parts of stannous chloride, 10-15 parts of thioglycolic acid, 5-10 parts of silver thiosulfate, 5-8 parts of calcium thiosulfate, 5-6 parts of aluminum sulfate and 5-8 parts of sodium hexametaphosphate. The heat-resistant electroplating solution has the advantages of heat resistance, non-corrosiveness, low preparation cost and the like.

Description

technical field [0001] The invention relates to the technical field of an electroplating solution, in particular to a heat-resistant electroplating solution. Background technique [0002] At present, in the process of mechanical processing, the anti-rust grease, cutting fluid, mechanical oil, lubricating grease, grinding fluid, demoulding machine, etc. adhered to the surface of parts are mixed with dust and grinding dust to form thick dirt . If the above dirt is not removed before heat treatment, it will be hard to clean when it is quenched and sintered into stubborn solid oil after degreasing and rust removal. During electroplating, bubbles adhere to it, causing the gas forming the coating to accumulate on the pinholes. It is difficult to thoroughly clean the above dirt during the existing electroplating process. Hydrogen bubbles tend to adhere to the dirt and are difficult to discharge, resulting in pinholes and pitting in the coating, and as the bubbles gradually grow, t...
