确定了侵蚀成分、硬度-强度特性和形状对 AISI 1020 碳钢侵蚀的影响。测试以 80 m s−1 的速度在两个撞击角度（α = 30° 和 90°）进行。使用维氏硬度 HV 为 115 至 3000 kgf mm−2 的五种成分的有角形状的颗粒。经确定，对于 HV> 700 kgf mm−2 的颗粒，侵蚀速率随着颗粒硬度的增加而增加，直至达到恒定速率。硬度是颗粒组合物脆碎度的量度。当颗粒足够强而不会在撞击 AISI 1020 钢表面时破碎时，侵蚀速率变得恒定。通过使用有角和球形钢腐蚀剂还确定，有角颗粒造成的腐蚀是球形颗粒的四倍。
The effects of erodent composition, hardness-strength characteristics and shape on the erosion of AISI 1020 carbon steel were determined. Tests were performed at a velocity of 80 m s−1at two angles of impingement (α = 30° and 90°). Angularly shaped particles of five compositions were used with Vickers' hardnessesHVfrom 115 to 3000 kgf mm−2. It was determined that the erosion rate increased with increasing particle hardness to a constant rate for particles withHV> 700 kgf mm−2. The hardness was a measure of the friability of the particle composition. When the particles were strong enough not to break up on impacting the AISI 1020 steel surface, the erosion rate became constant. It was also determined by using angular and spherical steel erodents that angular particles can result in four times more erosion than spherical particles.
