Abstract: An inlet valve is partially coated with a protective coating to resist corrosion and gas impingement when used in an internal combustion engine. The inlet valve has a hard cladding that is shaped to function as a valve seat. The hard cladding forms an interface with the valve head body, which is typically made of a softer metallic material than the hard cladding. The protective coating is bonded to the inlet valve and covers the cladding-body interface. The protective coating is resistant to corrosion, wear from gas impingement, and can withstand the high temperatures reached in internal combustion engines. Internal engines incorporating the valves are more durable and less susceptible to catastrophic valve failure. A method for making the inlet valves generally includes masking a portion of the valve stem and the valve seat, applying a protective coating to cladding-body interface, and curing the protective coating or otherwise bonding the protective coating to the inlet valve.
