TECHNOLOGY OF TITAN ALLOYED DIAMOND-LIKE COVERS
It is used to strengthen small-sized instruments, calibers, stamps, filiers.
Technology peculiarities There has been developed technology of putting titan alloyed diamond-like covers. Such covers are formed by a complex method, combining both simultaneous setting of carbon layers with the help of impulse vacuum-arc charge, and alloying metal atoms from ionizing streams. Cover hardness and the module of their elasticity depend on metal concentration in a cover.
Advantages and technical characteristics The plotting of wear-resistant coatings on the basis of ñarboneum on working surfaces of dies of cutting down and edging of integral chips augments their stability in 3-4 times (resource constitutes up to 90-120 thousand instruments). The economic efficiency consists also in cutting on 75 % of an amount of repairs, practical absence of a wear of working surfaces during normative maintenance of equipment. At holding trials on the "Integral" (Minsk) the annual economic benefit at the expense of increase of a resource of equipment has constituted 65 thousand US dollars.
Main technical characteristics · cover thickness up to 2mkm; · titan part up to 50 vol. %; · there are no exfoliations after 10000 cycles of wear; · under different vacuum metal filling coefficient of dry friction can vary from 0.1 to 1.4; · ecologically safe standard equipment is used to produce the cover.
The technology is a team-work of the Educational establishment “Gomel Francisk Skorina state university” and the Educational establishment “Belarus university of transport”. |
