Production of a valve seat used for a cylinder head of internal combustion engine comprises fusing an additive material made from an alloy or a mixture of an aluminum-lead alloy and a further component at a certain point on a cylinder head

摘要

The invention relates to a method for the production of a valve seat (5) for a cylinder head of an internal combustion engine. According to said method, an additional material is melted with the cylinder head by applying energy in the site in which the valve seat (5) is to be formed. An alloy or a mixture consisting of an aluminum-iron alloy and at least another component is used as additional material.
