理を行った場合にも同様の問題を生じる。However, in conventional hole sealing treatment using a laser beam, ceramic components, especially carbide ceramics, that make up the cermet have a high laser absorption rate, while metal substrates have a low laser absorption rate. Only the components are heated and evaporated, leaving large pores on the surface of the cermet and causing cracks in the cermet. A similar problem occurs when sealing a preformed cermet itself using a laser beam.
