Abstract
【解決手段】 本発明は、自溶合金皮膜の表面に磁石を接触、あるいは近づけ、その際の吸着性の有無、あるいは吸着力の強弱など磁性の違いを調べることにより、または透磁率測定装置により透磁率の大小を調べることにより、皮膜の良否を評価するものである。

Description
Claims (6)
- 自溶合金を母材表面に溶射被覆し、その後、溶融処理された皮膜の緻密性や母材との結合性などに基づく良否を磁性(透磁率及び又は吸着性)の違いによって非破壊で評価する方法。
- 自溶合金を母材表面に溶射被覆し、その後、溶融処理された皮膜の表面に磁石を接触させ、あるいは近づけ、その際の吸着性の有無、あるいは吸着力の強さを調べることにより皮膜の良否を評価する方法。
- 自溶合金を母材表面に溶射被覆し、その後、溶融処理された皮膜の表面を透磁率測定装置により透磁率を測定し、その値の大小により皮膜の良否を評価する方法。
- 請求項2の方法により皮膜の吸着力を示さなかった場合、請求項3の方法で皮膜の良否を評価する方法。
- 請求項1及び2において、自溶合金溶射皮膜は、JIS H8303に規格されているSFNi1〜5、SFCo1、2、SFWC1〜4、あるいはこれらに準拠した組成、性状、特性を有した粉末を原材料として溶射被覆され、その後、ガス炎、加熱炉、高周波、抵抗加熱装置などの熱源によって加熱・溶融された皮膜を対象とすることを特徴とした自溶合金溶射皮膜の非破壊評価方法。
- 請求項1及び2において、母材として、鉄鋼材料、非鉄材料等、自溶合金溶射皮膜の溶融温度よりも高い融点を有する金属材料を対象とすることを特徴とする自溶合金溶射皮膜の非破壊評価方法。
