Abstract
The work presents results of study of gasoabrasive wear of a wide range of thermoplastic polymers. A relationship is found between the conditions of synthesis of thermoplastic polyurethanes and their structure, physicomechanical, and triboengineering characteristics. Methods of predicting wear of polyurethane thermoplastics in a flow of abrasive particles are developed with account of varying structural parameters (concentration of rigid blocks, molecular mass), origin and type of initial components, and service characteristics (flow velocity of abrasive particles, angle of attack). Recommendations are given for enhancing abrasive resistance by synthesizing initial materials with preset properties.
