The Experimental Characteristics and Evaluation of Nylon-12 in Erosion Process

Polymer materials are used in a wide range of applications. The erosion properties of nylon-12 were analyzed in this study. Randomly-shaped sand (SiO2) particles of various sizes (300–355 lm, 355–500 lm, and 500–600 lm) were selected as erosive elements. Impingement angles between 15 and 90_, imping...
