Summary:PROBLEM TO BE SOLVED: To provide a cold spray coating process, in which there is no waste of a babbitt material without a long time or damage on components at low costs, and a coated article.SOLUTION: The cold spray coating process includes the steps of: positioning a cold spray nozzle 102 relative to a bearing assembly 101; rotating the bearing assembly 101; and directing a powdered babbitt material 103 through the cold spray nozzle 102, to a surface of the rotating bearing assembly 101. The powdered babbitt material 103 adheres to the surface of the rotating bearing assembly 101, forming a coating on the surface. In another cold spray coating process, the cold spray nozzle 102 may be positioned relative to the bearing assembly 101, and rotated instead of the bearing assembly 101. Another cold spray coating process includes a step of monitoring properties of the coating on the surface of the bearing assembly 101 with a coating monitor 110. 【課題】時間がかからず、低費用で、部品に損傷を生じず、バビット材料の無駄がないコールドスプレー式塗工法及び塗工物品を提供する。【解決手段】コールドスプレー式塗工法は、コールドスプレーノズル１０２を軸受アセンブリ１０１に対して位置決めするステップと、軸受アセンブリ１０１を回転させるステップと、コールドスプレーノズル１０２を通して粉末バビット材料１０３を回転軸受アセンブリ１０１の表面に導くステップとを含む。粉末バビット材料１０３は回転軸受アセンブリ１０１の表面に付着し、表面に皮膜を形成している。別のコールドスプレー式塗工法は、コールドスプレーノズル１０２を軸受アセンブリ１０１に対して位置決めして、軸受アセンブリ１０１の代わりにコールドスプレーノズル１０２を回転させてもよい。別のコールドスプレー式塗工法は、軸受アセンブリ１０１の表面の皮膜の特性を皮膜モニター１１０によって監視するステップを含む。【選択図】図１
