To apple ceramic coating on the equipment surface can have many
benefits . Such as high hardness, high temperature resistant,
corrosion resistance, salt fog resistance. Effect is much better
than common electroplating. It works well in ocean industry, food
machinery, water conservancy and hydropower, aerospace and other
industries.
