摘要

PPROBLEM TO BE SOLVED: To prevent the occurrence of crack by melting an interface between a clad material and a base material at starting the machining of a laser clad to secure the welding strength without producing a lack of build-up at the machined terminal end of the laser clad. PSOLUTION: This seat material for a laser clad valve seat is arranged on a valve seat forming site 2 of a cylinder head 1. It is melted by the irradiation with laser beams hv and built up on the valve seat forming site 2 to form a laser clad valve seat. The seat material 9 includes a ring part 9A formed of metal powder, a laser irradiation starting part 9B formed with a cutout portion 10 in part of the ring part 9A, and a laser irradiation terminal end part 9C rising from the ring part 9A above the laser irradiation starting part 9B. The laser irradiation terminal end part 9C is formed on the laser irradiation starting part 9B in an overlapped manner. PCOPYRIGHT: (C)2010,JPO&INPIT

要解决的问题：在开始加工激光熔覆层时，通过熔化熔覆层材料与基材之间的界面来防止裂纹的发生，以确保焊接强度而不会在机械层上产生堆积激光熔覆的终端。

解决方案：这种用于激光熔覆阀座的阀座材料布置在气缸盖1的阀座形成部位2上。通过激光束hv的照射而熔化，并堆积在阀座形成部位2上。形成激光熔覆阀座。座材9包括：由金属粉末形成的环部9A;在环部9A的一部分上形成有切口部10的激光照射开始部9B;以及从该环部9A上方突出的激光照射末端部9C。激光照射开始部9B。激光照射末端部9C以重叠的方式形成在激光照射开始部9B上。
