Nano-structured composite surface coatings
■ Ultra-hard coatings are sought by a growing number of industrial sectors, which are pushing back the limits of the materials used. The mechanical industry as a whole is constantly looking for harder materials that resist better to friction or very high temperatures. Manufacturers of cutting tools, cylinder heads for vehicles, clutches, brakes, turbine blades, pumps or rotating machines are the first to be concerned by these innovations, which are pushing back the limits of use of their products by considerably improving their life span. Nano-structured composite surface coatings represent a major qualitative opportunity among emerging innovations.
Written by one of the best French academic experts in the field, this new survey first of all recalls aspects related to the strengthening of the mechanical properties of materials by discussing the interest of hard materials to protect surfaces from wear, and then the improvement of the mechanical properties of polycrystalline materials. After recalling the characteristics of intrinsically hard materials (diamond and cubic boron nitride, heterostructures, multi-layers and super-networks), the author describes and discusses surface coatings applied through vapour deposition, detailing their properties and insisting more particularly on titanium carbide coatings and multi-layer titanium-titanium carbide coatings.
The third part is a thorough state of the art review describing existing hard nano-structured composite coatings or those being developed. Aspects related to the preparation of coatings, nano-crystalline alloy coatings, nano-composite coatings based on nitrides and hard and ultra-hard nano-composite coatings are covered. Lastly, the fourth part concerns lubricant nano-composite coatings: chrome-carbon coatings applied with electrolysis, nickel-phosphorous-teflon coatings applied by electro-chemical reduction without electrodes, composite coatings based on carbon and on molybdenum disulphide are described and discussed.
Illustrated throughout with concrete examples of use and feedback from industrial experience, the result of very active technological watch activities, this survey provides readers with quality information and an expert summary with which to choose the best solutions for their own applications and to anticipate upcoming technological developments.
