Witryna13 sie 2024 · The coatings obtained with PVD techniques have shown considerable erosion resistance when compared to other coating techniques due to the exceptional homogeneous deposition and the elimination of additional treatment on the thickness and surface smoothing, necessary to increase the coating’s wear resistance . WitrynaIdeal in locations where material impact, impingement wear and directional changes are causing excessive wear or material deflection is required. REDCO™ POLYURETHANE COATINGS Polyurethane coatings are a cost-effective coating option for a variety of substrates. Learn More.
WitrynaFor solid impingement erosion at a shallow angle of attack where the wear is similar to that of abrasion, high hardness coatings are required. For solid impingement angles near 90 coating toughness becomes more important. For cavitation and liquid impingement generally, a coating with good surface fatigue resistance is needed. Witryna16 mar 2024 · Therefore, in this work, the lower angle of 45° was responsible for greater erosion wear of the surface of the coating deposited at 400 A. In addition, as the arc current was increased, the hardness and brittleness of the surface increased, decreasing the erosion rate of the plasma spray coating for the erodent impingement angle of 45°.
