Hydraulic components are coated by thermal spraying to protect them against cavitation erosion. These coatings are built up by successive deposition of single splats. The behavior of a single splat under mechanical loading is still very vaguely understood. Yttria-stabilized zirconia (YSZ) and stainless-steel splats were obtained by plasma spraying onto stainless steel substrates. The velocity and temperature of particles upon impact were measured and the samples were subsequently exposed to cavitation erosion tests. An acoustic cavitation simulation estimated the water jet velocity and hammer stresses exerted by bubble collapse on the surface of the specimen. Although the results suggested that high stress levels resulted from cavitation loading, it was clear that weak adhesion interfaces played a crucial role in the accelerated cavitation-induced degradation.

通过热喷涂对液压组件进行涂层，以保护其免受气蚀的影响。这些涂层是通过连续沉积单个碎片而形成的。在机械负载下单个splat的行为仍然非常模糊。氧化钇稳定的氧化锆（YSZ）和不锈钢镀层是通过等离子喷涂到不锈钢基材上获得的。测量了撞击时颗粒的速度和温度，随后将样品进行空化腐蚀试验。声空化模拟估计了水的喷射速度和气泡破裂在试样表面上施加的锤应力。尽管结果表明，高应力水平是由空化载荷引起的，
