摘要： A raw material powder having particle sizes of not more than 125 μm and preferably not more than 75 μm, such as a powder of an alloy of Co-32% Ni-21% Cr-7.5% Al-0.5% Y is thermally sprayed onto surfaces of shroud members of a shroud to form a coating. The high velocity oxygen-fuel thermal spray method is used as the thermal spray method. In the obtained coating, the porosity is 5% to 30% by volume and the oxygen content is not more than 2% by weight. In particular, when the raw material powder has particle sizes of about 40 μm, it is possible to obtain the coating which has an extremely small oxygen content of about 0.5% by weight.

摘要： The composition of a hard-facing welding material to be overlaid onto a cast iron base metal followed by a supercooling treatment for hardening must lie above a line LA in a Schaeffler's structure diagram which is represented by a Cr equivalent and a Ni equivalent. On the other hand, if the base metal is preheated, the carbon precipitation line will be at the Ni equivalent of 34 (LC1), and the Cr equivalent will thus be above 4. However, if the Cr equivalent is above 4, there will occur cracks after welding (examples in which cracks occurred are shown by square marks represented by a in FIG. 1). As a solution, the carbon precipitation line was raised up to the Ni equivalent of 38 without preheating the base metal, and the Cr equivalent of the welding material was made to be 4 or less.
摘要翻译：要覆盖在铸铁母材上的硬面焊接材料的组成，然后进行用于硬化的过冷却处理，必须位于舍弗勒结构图中的线LA之上，该结构图由Cr当量和Ni当量表示。另一方面，如果贱金属被预热，则碳沉淀线的Ni等效值为34（LC1），Cr当量将高于4.然而，如果Cr当量高于4，则发生焊接后的裂纹（发生裂纹的实施例以图1中由a表示的方形标记表示）。作为解决方案，将碳沉淀线升高至不等于贱金属的Ni当量38，并将焊接材料的Cr当量设为4以下。
