Results of tribological tests of samples of dental materials with protective coating of silicon carbide known as "Pantsyr"

Tribology tests of standards in the conditions of the Proof-of-concept laboratory of functional surfaces covered and uncovered by sheeting «Pantsyr» from the carbide of silicon was conducted by the method of the measuring skidding on the automated machine offriction(tribometer) of TRIBOMETER of firm CSM Instruments. The results of tribology tests treated by means of the computer program Instrum X (CSM Instruments, Switzerland). Profilometric research offurrows of wear on separate standards with coverage and without him with the purpose of determination of area of section offurrows for a subsequent calculation the brought wear over of standards conducted on the optical profilometer of WYKO NT1100 firm Veeco(THE USA), Among studied it is necessary to distinguish a with coverage (Plastic(Ftoraks)), that at the indicated terms of tests showed very subzero(less than 0,1) constant of friction at his insignificant amplitude. It testifies to set constant of friction that did not almost change during all experiment (15000 cycles equal to the year of the use ofprosthetic appliance a patient For (Plastic (Ftoraks)), the brought wear over, that made 9*10 -6мм 3/(Н*м) The same standard without coverage showed a wear more than twice higher ((1.4-0,9)/0.9), was expected.
