This document reports on the sliding characteristics of automotive engine sliding bearings with low friction properties. It includes the concept of low friction bearings, bearing structure, wettability with lubricants, non-adhesiveness, as well as the starting friction coefficient from bearing performance tests and seizure tests. Engine bearings are required to respond to high surface pressure due to miniaturization and width reduction, low friction, and lead-free requirements, and even higher bearing performance is desired. 【Contents】 ■ Overview ■ Introduction ■ Low Friction Bearings ■ Bearing Performance Tests ■ Conclusion *For more details, please download the PDF or feel free to contact us.

This document discusses the effects of surface treatment on the tribological properties of DLC (Diamond-Like Carbon). Focusing on Fine Particle Bombarding (FPB), it introduces how the surface modification of practical substrates affects the friction characteristics and adhesion of DLC-coated materials. Surface treatment (modification) is a field that is expected to expand increasingly, and it is believed that various composite treatments, not limited to WPC treatment and DLC composite treatment, will become important.
