Description
Cは、肉盛層の機械的強度、硬度を向上させるために必要である。しかしながら、1.0質量%を超えると、肉盛溶接時に割れが発生する。
Siは、2.0質量%を超えると、溶接時に割れが発生し、靭性及び硬度が低下する。なお、溶接金属を脱酸するためにSiは少なくとも0.2以上添加するのが好ましい。
Mnは、3.0質量%を超えると、硬度が低下する。なお、溶融金属を脱酸するためにMnは少なくとも0.5質量%以上添加するのが好ましい。
Crは、上地自溶合金溶射層をフュージングした際に、そのフュージング熱を受熱してオーステナイト領域まで昇温され、フュージング後に冷却されることにより、組織がオーステナイト組織からマルテンサイト組織に変わるため、硬度が向上する。Crの含有量が1質量%未満になると、上述の効果が得られない。Crの含有量が15質量%を超えると、オーステナイト組織が多くなり硬度が大きく低下する。好ましくは、Crの含有量は8.0質量%以下である。Crの含有量を8質量%以下に制限することにより、オーステナイト組織の増大による硬度低下を、十分に抑制することができる。
Cを0.4%以上含有させると割れが生じやすくなるが、Nbを添加することにより、Cを多量添加することによる割れの発生を抑制することができる。また、肉盛溶接時にNbCからなる炭化物が析出し、フュージング熱による硬さ低下を防止でき、結晶粒の粗大化防止と軟化抵抗が得られる。Nbの含有量が0.5質量%未満になると、上述の効果が得られない。Nbの含有量が5.0質量%を超えると、硬度が低下する。すなわち、Nbが5%を超えるとマトリクス中のCの減少量が多くなり、逆に硬さが低下する。
Moは高温硬度を増す効果があるが、0.1%未満だと効果がない。5.0%超添加だとその効果は飽和し、著しい硬度向上効果が望めない。
Vは高温硬度を増す効果があるが、0.1%未満だと効果がない。3.0%超だとその効果は飽和し、著しい硬度向上効果が望めない。
Coは高温硬度を増す効果があるが、0.5%未満だと効果がない。5.0%超だとその効果は飽和し、著しい硬度向上効果が望めない。またCoは高価であるため、上限値を5.0%とした。
Wは高温硬度を増す効果があるが、0.5%未満だと効果がない。5.0%超だとその効果は飽和し、著しい硬度向上効果が望めない。
Tiを添加することにより、結晶粒粗大化防止とTiCからなる炭化物が析出する。0.1%未満だと効果がない。また、1.0%超だと、Tiの歩留りが著しく悪くなる。
