溶射加工による機能性材料の開発

抄録

The　new　materials　which　are　composed　of　metals　and　ceramics　have　many　interesting　and　useful properties　in　mechanical,　electrical　and　chemical　fields.　Recently,　a　great　deal　of　attentions　have been　held　to　the　potential　utilization　of　these　properties. In　this　paper,　the　forming　process　for　such　materials　was　researched　using　a　low　pressure　plasma spraying　equipment　including　two　independent　metal　and　ceramic　powder　supplying　devices　and　a plasma　jet　flame. Using　quality　engineering　approaches,　the　generic　function　of　plasma　spraying　was　used　for　evaluation.　After　the　optimization,　metal　and　ceramic　materials　can　be　sprayed　under　the　same　condition.　Also,　it　is　possible　to　produce　the　sprayed　deposit　layer　of　any　metal/ceramic　mixing　ratio　for both　dispersed　type　and　inclined　type　products.
