【Abstract】 The development of the ceramic coat plug valve core which substrate uses 45 steel is introduced.The ceramic coating organization is tiny,its crystal grain grows consummates,the union intensity is high,the surface contours isgood,theremaining stress is low,The step configur-ation structure of spread ceramic coating has advantage to keep the lubrication in,thus the wearing resistance and erode resistance of the valve core working surface is enhanced.更多还原
