Schumacher Company has seventy-five years of Hard Chrome plating knowledge and expertise. With some of the largest Hard Chrome plating tanks in the United States, our capabilities allow us to take on the difficult jobs that our competitors can’t.
Unlike many of our competitors we also specialize in Hard Chrome plating I.D. components. We have the skills to construct internal auxillary anodes to precisely Hard Chrome plate your internal components to meet customer requirements.
In addition to its hardness, Hard Chrome has the added advantage of an extremely low coefficient of friction. Only one third of the force is required to slide a Hard Chrome plated block across a cast iron surface as compared to steel block.
A Hard Chrome plated surface tends not to seize, gall, or cold weld to another metal surface when the two are rubbed together under pressure.
Due to its non-galling tendency and its low coefficient of friction, Hard Chrome performs well on parts moving in contact with other parts and surfaces subjected to abrasive and corrosive wear from metallic or nonmetallic surfaces.
