Highly Effective Protective Ion-Plasma Coatings for Cutting Tools and Friction Assembly Parts


In the line of developing new technologies for surface modification of metals and alloys, IPMash NAS of Ukraine developed technologies of thin wear-resistant coatings based on refractory compounds. Their application ensures high wear resistivity and frictionless rubbing surfaces under excessive thermal and force effects, and insufficient lubrication. For example when using cutting and stamping tools; in friction assemblies of heavily loaded units, etc. Ion-plasma coatings and technologies of their production allow dramatically reduce seizing between rubbing parts and between tools and machined materials, due to such coatings, the durability and reliability of friction assemblies and cutters increases 8-50-folds.

Innovative Aspect and Main Advantages

Technologies of ion-plasma coatings allow obtaining coatings with low adhesive activity – making it possible to control seizure of contacting surfaces during friction and cutting. Such coatings increase many-fold the durability and reliability of both friction assemblies and cutters, and reduce the cost of making new parts and tools with usage of expensive materials. It increases the serviceability of brittle superhard tooling materials, allows developing high-performance tools for working hard-to-machine metals and alloys. These technologies in engine building increase the service life of internal combustion engines by 10 times, and reduce their cost, as compared to the current one, by 20 %.

Areas of Application


Stage of Development

In-depth research has been conducted in the physics of solids, low-temperature plasma, and the physics of cutting and friction. Principles have been formulated and theoretical basics have been worked out for obtaining highly effective ion-plasma coatings. Experimental research has been focused to improving the technology of obtaining protective coatings for cutters and friction assembly parts. Documents are being drafted for patenting in Ukraine.
