Wear of Flame-Sprayed Ni-Cr-B-Si Powder Coating on Journal for Seal Contact
Flame-sprayed techniques is used in this paper to coat Ni-Cr-B-Si powder on low-carbon steel or bearing steel materials of the journal surface. The wear tester is used to explore material properties of the binding capability, surface hardness, wear and friction within each layer depth. The normal fo...
