ABSTRACT:
A method of producing an exhaust valve for a diesel engine comprising the steps of cutting a part of a valve or valve seat body, depositing or spraying onto the cut part a mixture of grains of ceramics and metals, and varying the proportion of grains of ceramics and metals during the deposition or spraying so that the deposited or sprayed layer will vary in content of metal and ceramics with the proportion of ceramics increasing with the increase in height from the valve or seat body of the coated layer, and then subjecting the coating to pressure of 3 to 7 Kg/mm.sup.2 and concurrently heating the coating to 700.degree. to 800.degree. C., thereby to produce a contact surface which forms the contact point between the valve and valve seat which has better adhesion, is close to the body, and has better corrosion resistance, anti-invasion properties, and good thermal shock resistance.
