Experimental Study of Abrasive Waterjet Nozzle Candidate Materials

Abstract

With the increasing application of abrasive water jets in industry, developing new materials to improve the lifetime of focusing tube nozzles is becoming more important in developing the technology. In order to have a better understanding of the controlling factors in nozzle wear and to investigate candidate nozzle materials, a series of AWJ tests were performed on several hot pressed, hard materials. In these tests, different angles of attack between the AWJ beam and testing specimen were chosen to simulate the actual abrasive impact condition in the focusing tubes. ROCTEC100 and 500 were also tested as reference materials. The wear mechanism was analyzed by characterizing the wear surface using SEM. The volume losses of the different materials were compared and the effects of the materials' properties on the lifetime of the focusing tube were analyzed.
