苜蓿草粉对金属材料的磨料磨损试验(Experiment of Metal Materials Abrasive Wear for Alfalfa Powder)
苜蓿草粉 金属材料 磨料磨损
2009/11/24
选用与环模制粒工况相似的磨料磨损试验机,以苜蓿草粉为磨料对试样进行磨料磨损试验。通过磨后表面的硬度和化学成分测定、微观结构和表面形貌观察,考察了苜蓿草粉对4种金属材料的磨料磨损。结果表明,4种材料的体积磨损量由小到大依次为3Cr13、9SiCr、45号钢、HT200,试样的磨损表面发生了物理和化学变化。“软磨料磨损”中伴有 “硬磨料磨损”的特征,显微切削和应变疲劳剥落为其主要磨损形式。
