After machining, the sealing surface is subjected to tungsten carbide HVOF high-temperature thermal spraying to enhance its corrosion resistance and high temperature resistance. After ultra-high precision polishing, it can present a mirror effect, and the precision of the machined plane can reach 0.001um or more, maintaining a high level of precision machining capability in the industry.
