苜蓿草粉对金属材料磨损性能的影响

以‘甘农三号’紫花苜蓿草粉为磨料,运用正交试验方法,在磨料磨损试验机上研究了转速、负荷、草粉粒度对45#钢磨损性能的影响.通过直观分析和极差分析得出:影响45#钢磨损性能的主要因素为转速,次要影响因素为负荷和草粉磨料粒度;草粉磨料磨损试验最佳工况为转速(100±2)r/min,负荷40.5 N,磨料粒度6 mm.

Effects of alfalfa meal on the wear properties of metal material

Taking alfalfa meal of the cultivar 'Gannong No.3'as the abrasive,and orthogonal test as the method,effects of rotation speed,load and the size of the meal on the 45# steel wear performance were studied by using abrasive wear test machine.The results of the direct-viewing analysis and the range analytical analysis showed that rotation speed was the main factor that affected the wear properties of 45# steel,thus load and the size of the meal were secondary factors.The best conditions of meal abrasive wear test were as rotation speed(100±2)r/min,load 40.5 N and abrasive particle size 6 mm.
