| Abstract: | Fe547B alloy powder spray melted coating was sprayed on high temperature and high process valve sealant made from 12Crl MoV steel with oxyacetylene flame put in fluxing compound one- step method spraying process, testing and study for spraying process and hardness, age - hardening characteristic, thermal durability and scratching resistant were carried out. The results have proved that healing up of cracking on high temperature and high process valve sealant by spraying Fe547B alloy powder is certainly feasible. |
