Abstract
Description
本発明は、内燃機関に用いられる可動壁部材であって、母材上に、最表面が触火面となる耐食層を有し、前記耐食層が、Ni50質量%以上60質量%以下、Cr40質量%以上50質量%以下を含む合金を用いて多層に肉盛溶接されてなる可動壁部材を提供する。
本実施形態では、船舶用ディーゼルエンジンの排気弁を例として説明する。図2は、本実施形態に係る排気弁の正面図である。図3は、図2の排気弁における触火面側の部分断面図である。
排気弁4のフランジ部4bの燃焼室側を向いた面(触火面側)に、緩衝層6および耐食層7を順に設ける。緩衝層6は、緩衝層6を構成する材料に適した方法で適宜形成されるとよい。
上記実施形態に従って耐食層を形成し、耐食層の各層のCr含有率を確認した。図7は、実験例に係る可動壁部材の部分断面図である。排気弁4(母材)の材料は、15Cr−14Ni−2Si−2.5W−0.4C(SUH31)とした。緩衝層6は、炭素量が0.09質量%を超える合金鋼を用いて、MAG溶接により形成した。緩衝層6は、4から5層構成(総厚さ10mmから12mm)とした。
図8は、本実施形態に係る排気弁の正面図である。本実施形態は、排気弁(母材)4上に直接耐食層17が形成されている。それ以外は、第1実施形態と同様の構成である。
