Resistance to surface wear 表面耐磨
surface wear-resistance composites 表面耐磨复合材料
This surface has extreme hardness (60 RC. ), excellent wear and corrosion resistance, and low coefficient of friction.
这表面有极高的硬度（60局。），耐磨性和耐腐蚀性，低摩擦系数。
Aluminum Oxide Specific gravity 2.4 Moh hardness 3. More a filler than an abrasive. Tends to fade, but has good wear resistance. Will polish the opposing surface.
氢氧化铝比重2.4莫氏硬度3。比磨料加得更多的填充物。有衰退趋势，但耐磨性好。将抛光对偶。
Weathering steels should be used with caution as their resistance to corrosion is often significantly reduced by mechanical wear att he surface.
耐候性钢材应谨慎使用，因为表面机械磨损经常会大幅度降低其抗腐蚀能力。
