Problems solved by technology

[0002] At present, the application of valves plays a key role in many fields. Because copper valves have strong corrosion resistance, copper valves are widely used, but copper valves also have defects, such as: short service life, low abrasion resistance, and poor high temperature resistance. etc., in view of these defects, the present invention proposes a bronze valve friction-resistant alloy coating and its coating process, which can improve the friction resistance and high temperature resistance of copper valves, increase the service life and reduce costs
