Methodology development of the materials erosion tests

The research paper describes a centrifugal stand and a methodology of materials testing for erosive wear in a simulative medium, which contains water, abrasive particles, and corrosive-active elements, which are analogous to the formation fluid of oil wells. There are test results in water with abrasive of four types powder materials based on iron and copper, alloyed with N1, Cr, Mo. The experiment parameters: the fluid jet speed is 11…16 ms⁻¹, the impact angle is 45°…90°, silica sand and corundum particles of different dispersion F100, F40, F24. A linear dependence of the relative wear rate on the experiment time at various impact was revealed. The wear of powder materials in liquid with corundum F100 is approximately 5 times more than with similar fraction silica. The material PK90N4MG2KD15 has the greatest erosion wear resistance under the influence of F100 fine particles. (paper)
