Cermet coating pump sets of parent material: stainless steel, carbon steel wear layer: alumina ceramic hardness: 70-- 75HRC Thickness: 5-10mm Porosity: 0.02% Features: compact, high hardness, wear resistance in the oil, gas exploration and used in the drilling process is a key piece of equipment such as drills, shafts, bearings, bushings, grout pumps, etc., are subject to mud, minerals and other abrasive two-body and three-body abrasion wear ceramic coating project, and by the water, containing S ( or H2S gas) crude oil or natural gas corrosion. Ceramic coating for components used in such harsh conditions, the use of manufacturing high-alloy metal, its potential is limited, and high maintenance costs. Effective approach is to use synthetic diamond production, but the cone mosaic drilling teeth are usually made of alloy hardening, its resistance to sand abrasion of rock performance is lower than diamond. The diamond drill will wear vertebral cobalt tooth loss, resulting in premature failure cone bit. To replace the new drill bit cumbersome, you need to drill one by one to upgrade from a few hundred meters or even several kilometers deep underground to the surface to be replaced. Obviously ceramic coating production, improve the wear resistance and service life of the cone drill for oil exploration and drilling have significant economic value. For this reason, the use of explosion spraying spraying WC-15% (by mass) in the cone drill cone Co cermet coating achieved the expected significant effect. As another example, the rig components manufactured with hardened steel (Rockwell hardness of 49 to 52), the use of air plasma spraying (APS) Cr2O3 ceramic coating, significantly extended service life. What are the main oxide ceramic material? Oxide ceramics are commonly used ceramic coating material. Classified according to their composition, mainly alumina oxide, ho Department, titanium, chromium, mullite, spinel ceramics. Have a high melting point oxide, mostly above 2000 ℃. The vast majority oxide in an oxidizing atmosphere is stable, mostly oxides having heat insulating properties and electrical insulating properties, strength characteristics in a high temperature environment. The most important feature in the oxide ceramic thermal spray process, it can be sprayed directly in the atmosphere, does not require a vacuum or protective atmosphere and other conditions, which for equipment manufacturing, paint shop has a great design and cost benefits. Therefore, the oxide ceramic thermal spray technology has become the most widely used, up to the amount of the ceramic coating material. An oxide-based ceramic thermal spray coatings wide range of applications, including use of its chemical properties and corrosion candle metallurgy petrochemical, metallurgy, etc; use the wear resistance of the machinery, transportation field; use the heat aerospace engine thermal barrier properties of the field; and other utilization of electrical insulation, functional coating magnetic field shielding, a solid electrolyte, infrared radiation and other properties.
