    摘要:

    對TC4合金和P110油管鋼在不同溫度下的摩擦磨損性能進行對比研究，分析其摩擦系數(shù)、磨損率和磨痕形貌隨溫度的變化規(guī)律，探討磨損機制。結(jié)果表明：P110油管鋼的耐磨性明顯優(yōu)于TC4合金，TC4合金的耐磨性隨溫度的升高無顯著變化，磨痕呈犁溝形貌，在較低溫度時的磨損機制為剝層磨損、黏著磨損和疲勞磨損，在較高溫度時為剝層磨損、黏著磨損和氧化磨損；P110油管鋼耐磨性隨溫度的升高而降低，在較低溫度時磨痕呈磨坑形貌，磨損機制為剝層磨損和磨粒磨損，在較高溫度時磨痕形貌呈犁溝形貌，主要為剝層磨損、黏著磨損和氧化磨損。

    Abstract:

    The friction wear properties of TC4 alloy and P110 tubing steel were comparatively studied at different temperatures. The changing rules of the wear rate, frication coefficient and topography of wear mark with the temperature were analyzed and the wear mechanism was also discussed. The results show that the wear resistance of P110 tubing steel excels obviously that of TC4 alloy. The wear resistance of TC4 changes a little with temperature rising and the wear mark is furrow morphology. The wear mechanism of TC4 alloy is delamination abrasion, adhesive abrasion and fatigue abrasion at lower temperature and delamination abrasion, adhesive abrasion and oxidation abrasion at higher temperature. The wear resistance of P110 tubing steel is decreased with temperature rising. The wear mark of P110 tubing steel is wear pit morphology and the wear mechanism is delamination abrasion and abrasive grain abrasion at lower temperature, while the wear mark is furrow morphology and the wear mechanism is delamination abrasion, adhesive abrasion and oxidation abrasion at higher temperature.
