Abstract
Description
特許文献1に開示された技術では、局所加熱装置によって溶融する硬質粉末同士が凝集し、盛金層内の硬質粒子が粗大化するため、盛金層の被削性が低下する虞があった。
Cr、Fe、Co、Ni、及びCuのうち1種以上の元素と、Mo、W、及びNbのうち1種以上の元素とを含有するシリサイドを硬質相として含む硬質粉末と、銅基合金からなるマトリクス粉末と、を含む盛金用粉末を基材上に供給しながら局所加熱装置によって溶融させつつ、前記局所加熱装置による加熱部位を前記基材に対して相対移動させて盛金層を形成するステップと、
前記基材上に形成された前記盛金層を切削加工するステップと、を備え、
前記硬質粉末は第1硬質粉末と第2硬質粉末とを含み、
前記盛金層を形成するステップにおいて、
前記第1硬質粉末と前記マトリクス粉末とを前記局所加熱装置によって溶融させて形成した溶融池に対して、前記第1硬質粉末とは別に前記第2硬質粉末を供給し、
前記第2硬質粉末の少なくとも一部を前記盛金層の内部に未溶解のまま残留させるものである。
また、被削性を向上させるために、前記第2硬質粉末の粒径を250μm以下としてもよい。
また、前記第2硬質粉末及び前記第1硬質粉末は、いずれも、Cr、Fe、Co、Ni、及びCuのうち1種以上の前記元素を10質量%以上、Mo、W、及びNbのうち1種以上の前記元素を15質量%以上、Siを2.0〜8.0質量%、含有してもよい。
基材と、
前記基材上に形成された盛金層と、を備えた耐摩耗部材であって、
前記盛金層は、
銅基合金からなるマトリクスと、
Cr、Fe、Co、Ni、及びCuのうち1種以上の元素と、Mo、W、及びNbのうち1種以上の元素とを含有するシリサイドを硬質相として含み、未溶解のまま残留した硬質粉末と、
Cr、Fe、Co、Ni、及びCuのうち1種以上の元素と、Mo、W、及びNbのうち1種以上の元素とを含有するシリサイドを硬質相として含む晶出粒子と、を有するものである。
また、被削性を向上させるために、硬質粉末の粒径が250μm以下でもよく、前記晶出粒子の粒径が100μm以下でもよい。
さらに、前記晶出粒子の硬さが前記硬質粉末の硬さよりも高くてもよい。
まず、図1〜図5を参照して、第1の実施形態に係る耐摩耗部材の製造方法について説明する。ここでは、エンジンのシリンダヘッドに形成するバルブシートを耐摩耗部材の一例として説明するが、耐摩耗部材はバルブシートに限定されるものではない。
図2は、第1の実施形態に係る耐摩耗部材の製造方法に用いるレーザ加工ヘッドの断面図である。
図3、図4は、第1の実施形態に係る耐摩耗部材の製造方法の詳細を示す断面図である。
図5は、盛金層を形成するステップにおける盛金用粉末の供給方法を模式的に示す側面図である。
なお、詳細には図5を参照して後述するように、第1の実施形態に係る耐摩耗部材の製造方法では、レーザ加工ヘッド40と別のノズルからも盛金用粉末を供給する。
表1に、実施例及び比較例に用いたマトリクス粉末及び硬質粉末の組成を示す。また、表2には、実施例及び比較例に用いたマトリクス粉末及び硬質粉末のビッカース硬さ(HV0.1)、液相線温度、固相線温度を示す。
被削性試験では、刃具としてTiCN超硬コートチップを用いた。プランジ加工条件は、切削速度V=80m/分、1回転当たりの送り量f=0.03mm/rev、切込み量t=0.5mmとし、300個の盛金層を加工した。
以上の通り、実施例は、比較例と同等の耐摩耗性を維持しつつ、比較例に比べ盛金層の被削性が劇的に向上した。
例えば、盛金方法として、上記実施形態において用いたレーザ盛金以外に、ガス盛金、プラズマ盛金等を用いることができる。
