Abstract:
1. A bearing component of steel, the bearing component having: at least one layer having a high hardness and a high current insulation property applied by at least one of a PVD (physical vapor deposition) process, a CVD (chemical vapor deposition) process, and a PECVD (plasma enhanced chemical vapor deposition) process (but excluding an ALD (atomic layer deposition) process or a plasma enhanced ALD process) at at least one surface region of said component, said at least one layer comprising a non-conductive oxide layer selected from the group of materials comprising an Al at least one ALD layer comprising at least one layer of a material deposited by an ALD process on said at least one layer having a high hardness and a high current insulation property, the ALD layer itself having a high current insulation property and comprising a material or layer structure selected from the group of materials comprising an Al
