Method for forming a valve seat of a cylinder head, and valve seat area of the cylinder head processed with the method

摘要

The invention relates to a method for forming a valve seat (1) on a cylinder head (2) of an internal combustion engine, with at least the following steps: providing the cylinder head (2) from a substrate material (7), at least partially pre-processing the valve seat (6), heating the Valve seat (6) up to the molten state, and introducing material into the molten bath which causes hardening of the substrate material (7). The invention also relates to a cylinder head, the valve seat of which is machined by the method.
