Abrasion Resistance of Thermoplastic Polyurethane in Abrasion Resistance Test Using Abrasives.
KOBUNSHI RONBUNSHU, 1992 ポリカプロラクトン, 4, 4'-ジフェニルメタンジイソシアナート, 1, 4-ブタンジオールからなる熱可塑性ポリウレタンのうち組成比の異なる2種類の試料について, 研磨材を用いた摩耗試験を行った. その結果, 硬さが小さく, 動的貯蔵弾性率 (E') の小さい試料が耐摩耗性が良好であった. また, 温度を上げた状態での摩耗試験の結果, 及び加圧下でのポリウレタンと鋼球の接触状態の観察から, E'の低い試料では, 研磨材との接触面積が大きくなり, 研磨材と一体となった層を形成するため, 耐摩耗性が向上するものと考えられた.

Effect of microstructure factors on abrasion resistance of high-strength steels
Research in Agricultural Engineering, 2014 Current development of high strength abrasion resistant steels is mostly oriented on high hardness, martensitic concept following the hypothesis that the abrasion resistance holds a proportional tendency with hardness.

Structural compressibility in 3d printed abrasion protection structures
Communications in Development and Assembling of Textile Products, 2020 Abrasion protection in exposed areas is a common method of extending the life cycle of textile products. To achieve sufficient abrasion resistance, the textile products are usually coated or partially printed with hard products.

Abrasion Resistance of Concrete [PDF]
ACI Journal Proceedings, 1981 This thesis describes an experimental study of the abrasion resistance of concrete at both the macro and micro levels. This is preceded by a review related to friction and wear, methods of test for assessing abrasion resistance, and factors influencing the abrasion resistance of concrete.
