Description
しかしながら、６価クロムを含有するめっき浴（６価クロムめっき浴）は、２５０ｇ／Ｌ程度という高濃度のクロム酸（ＣｒＯ ３ ）を含有するために酸化力が非常に高く、バレルめっき法でめっき処理を行う場合には、被めっき物への通電が断続的に遮断されるので、この際に析出したクロムめっき皮膜の表面が不導体化して、形成されるクロムめっき皮膜にクモリなどの外観不良や密着不良が生じるという問題点がある。このため、６価クロムめっき浴によるバレルめっきは非常に困難であり、工業的に実用化するには至っていない。 However, a plating bath containing hexavalent chromium (hexavalent chromium plating bath) contains a high concentration of chromic acid ( CrO 3 ) of about 250 g / L, and therefore has a very high oxidizing power. When processing, the power to the object to be plated is interrupted intermittently, so the surface of the chromium plating film deposited at this time becomes non-conductive, and the formed chromium plating film has poor appearance such as spiders. And there is a problem that poor adhesion occurs. For this reason, barrel plating with a hexavalent chromium plating bath is very difficult and has not been put into practical use industrially.
