Abstract
The article studies the characteristics of mill knives of high-speed steel HS 18-0-2-5 with as well as without МоС and Мо2С molybdenum carbide coating at plane milling of oak wood. The molybdenum carbide coating was deposited by arc vacuum physical vapor deposition (Arc-PVD). The knife edge wear was determined using a contour measuring system for determining the displacement of the cutting edge along the axis of the cutter wedge sharpness angle (WBW). Compared to a milling cutter with knives without coating, the molybdenum carbide coating improves the wear resistance of the knife blades and increases the cutting power by almost 40% when milling oak wood samples. The mills with the knife edges coated with the molybdenum carbides exhibited an average reduction in oak wood surface roughness Ra by 1.5–3 µm as compared to the bare tool in the entire range of applied feed rates and milling length. The laboratory tests of the wood-cutting tool covered with MoC coating prove that their durability has increased by 30% against the durability of the bare tool used in milling oak wood.
期刊介绍:
Journal of Friction and Wear is intended to bring together researchers and practitioners working in tribology. It provides novel information on science, practice, and technology of lubrication, wear prevention, and friction control. Papers cover tribological problems of physics, chemistry, materials science, and mechanical engineering, discussing issues from a fundamental or technological point of view.
