THERMAL SPRAY COATING, ENGINE HAVING THE SAME AND METHOD FOR DEPOSITING THERMAL SPRAY COATING
PROBLEM TO BE SOLVED: To provide a thermal spray coating capable of avoiding the peeling of the thermal spray coating due to heat stress and promptly lowering the elevated temperature of the thermal spray coating while maintaining thermal insulation properties, and a method for depositing the thermal spray coating.SOLUTION: The thermal spray coating includes a first thermal spray coating formed on the surface of an aluminum base material and a second thermal spray coating formed on the surface of the first thermal spray coating. In the first thermal spray coating, an inorganic material having a laminar crystal structure is dispersed into a Ni based alloy material, and an area ratio of the inorganic material to the cross section area of the first thermal spray coating is 40-80%. The second thermal spray coating includes SiOof 30-50 mass% and is a porous coating consisting of ZrO-SiObased ceramics. The pore area ratio of the second thermal spray coating to the cross section area of the second thermal spray coating is 30 to 80%.SELECTED DRAWING: Figure 1
【課題】熱応力により溶射皮膜が剥離することを回避するとともに、断熱性を維持しつつ、上昇した溶射皮膜の温度を迅速に下げることができる溶射皮膜および溶射皮膜の成膜方法を提供する。【解決手段】アルミニウム基材の表面に形成された第１溶射皮膜と、第１溶射皮膜の表面に形成された第２溶射皮膜とを有した溶射皮膜である。第１溶射皮膜は、層状の結晶構造を有する無機材料がＮｉ系合金材料に分散し、第１溶射皮膜の断面積に対して前記無機材料の面積率が４０％〜８０％にある。第２溶射皮膜は、ＳｉＯ２を３０〜５０質量％含有し、かつ、ＺｒＯ２−ＳｉＯ２系セラミックスからなる多孔質皮膜であり、第２溶射皮膜の断面積に対して、第２溶射皮膜の気孔の面積率が３０〜８０％である。【選択図】図１
