Ceramic material with improved wear resistance.
Ceramic material with high wear resistance and a zero coefficient of thermal expansion consists of a tungstate of zirconium. Has high structural and mechanical strength, incarnum effect – invariance sizes as during heating and cooling in a wide temperature interval from -100 to +200, almost “eternal” life.
Ceramic material with high wear resistance and a zero coefficient of thermal expansion consists of a tungstate of zirconium. He – tungstate Zirconia provides ceramics injury effect – the constancy of size as during heating and cooling in a wide temperature interval from -100 to +200 operating systems, and also provides such qualities as efficient performance in extreme conditions, high structural strength and light weight. Despite the fact that the ceramic material is ceramic, it has a unique high mechanical strength.
This ceramic material is used for manufacturing a new class of locking elements for pipelines of oil and gas complex and well withstand a pressure of 40 atmospheres. Shut-off valves designed to shut off the flow of hydrocarbons in the tube. Requirements to the materials of valves is very high, since its elements have the strongest load. Injury effect reduces friction any valves to almost zero, whereby the service life increases substantially, it becomes very long, “almost eternal”. This, in turn, will reduce the volume and frequency of costly repairs on gas and oil pipelines, caused by the replacement of the valving elements.
Ceramic material with high abrasion resistance and zero thermal expansion coefficient on the basis of zirconium tungstate has no analogues in Russia and in the world. The main problem is that the tungstate of zirconium is very difficult to enter into the ceramics. Previously in the world nobody did, but in the course of their studies, the inventors have found a technical solution to the problem determined the optimal content of tungstate of zirconium in the composition of ceramic and efficient method of sintering.
Ceramic material based on zirconium tungstate applies to nanomaterials the nano.
– high structural strength,
