土壤.勘察和試驗.普氏貫入試驗For this reason, protodrakonov scale of hardness of the cobalt crust is measured by impact crushing test and factors affecting its crushability are analysed, providing the basis for designing crushing devices
為此採用沖擊破碎試驗法測定了鈷結殼的普氏系數,並分析了影響其破碎強度的相關因素,為將來結殼破碎裝置的設計提供了依據。Abstract : the paper analyzes the wear resistance and anti - adhesion of 20 and 45 steel formed in austenitic ion - nitrocarburising and comparisons to the general ion - nitrocarburising. the experiment shows that austenitization - nitrocarburising can be carried out at 590 700, its wear resistance and anti - adhesion is the best at 630 , the worst at 660 and anti - adhesion is the best at 630 , the worst at 660 and the mediate at 570 600. with the help of raising processing temperature properly and speeding up the process the wear behavior can be improved
文摘:研究20鋼、 45鋼經奧氏體離子氮碳共滲后的耐磨性和抗咬合性,並與普通離子氮碳共滲后的作了比較,試驗表明:在570 700范圍內進行離子氮碳共滲后,其耐磨性和抗咬合性以630處理時為最佳, 660處理時最差,而570 600處理時則介於兩者之間,通過適當提高共滲溫度,再提高滲速,從而縮短共滲時間的同時,可以提高耐磨損性能。Proctor compaction test
