第2の実施形態は、溶射工程15において、図3に示すように、シリンダボア3内に溶射ガン7を回転させながら挿入してシリンダボア3の内面に溶射皮膜5を形成する際に、溶射ガン7の矢印Bで示す回転方向の回転数を所定値以上の例えば500rpmとする。このように、溶射ガン7の回転数を所定値以上に高めて回転速度を高めることで、前記した軸方向速度を高めたときと同様に、溶射ガン7を例えばシリンダボア3に対して1回転させたときのシリンダブロック1に対する溶射時の入熱量が減少する。すなわち、本実施形態では、シリンダボア3の内面に溶射皮膜5を形成する際に、シリンダブロック1に対する入熱量を抑えるよう調整してシリンダブロック1の温度を制御している。
第3の実施形態は、溶射工程15において、図4に示すように、シリンダボア3内に溶射ガン7を回転させながら挿入してシリンダボア3の内面に溶射皮膜5を形成する際に、シリンダブロック1を冷却する。シリンダブロック1を冷却することで、シリンダボア3の内面に溶射皮膜5を形成する際に、シリンダブロック1からの放熱量(シリンダブロック1が単位時間当たりの単位体積当たりに放出する熱量)が増大するよう調整してシリンダブロック1の温度を制御している。すなわち、本実施形態では、シリンダボア3の内面に溶射皮膜5を形成する際に、シリンダブロック1に付与される熱とシリンダブロック1から放出される熱との少なくともいずれか一方を制御して、シリンダブロック1の温度を制御している。
