|Broad Area of Technology:||Materials Science and Engineering, Coatings|
|Narrow Field:||Chemical Deposition of Coatings|
|Purpose:||The process permits obtaining wear-resistant coatings on tools in order to increase their life, performance and service characteristics|
Brief Description and Specific Features
The process involves the boiling of tools in an specially prepared aqueous suspension of compounds and other ingredients (the composition of the media and the treatment regime constitute the "know-how"). The ingredients are cheap and ecologically safe, and the suspension allows for multiple usage. For tools experiencing impact loads and/or local heating of the cutting edge during the service, subsequent heat treatment (tempering) is required. The treatment results in the formation of a soft film coating on the surface of the items, its thickness is about 10 mm. The coating acts as a solid lubricant during the work and is most effective for tools not subjected to heating and impact loading. refractory
Advantages Over Known Coatings and Coating Deposition Methods
Results of Testing in Industry
The use of coatings produced by the developed process gives an opportunity to increase the service life of high-speed and hard-alloy cutting tools and stamps by the factor of 1.5-4.
Examples: the increase of service life of processed tools, times: ·
Drills purchased from the German company "Stock" were processed by the developed technology. Testing revealed an increase in the service life by the factor of 1.8. Industrial testings of this process on "Daewoo Motor Poland" and Slovak companies "Skloplast", "ZVL-LSA Skalica", "Povazska strojarne" have shown an increase in the service life of screw taps, knives, punches and drills by the factor of 2 to 3.
When used for stamps and dies, the coatings permit eliminating adhesion.
The process is easy to implement. It has been tested and is used by more than 10 enterprises in Belarus and Russia.
