In the paper the author relates systematically the research fruits in the program of Research on Sand Slurry Abrasion Mechanisms of Dredging Conditions and New Wear-Resistant Materials. The main contents and innovations are listed as follows.Summarized and analyzed are the wear researches and developments, and the methods of increasing materials wear-resistance. From the viewpoint of the characteristics of two-phase liquid sand slurry wear, combined with the examination and study on easily damaged workpieces, the wear failures basic rules are pointed out, of the pump shell and the cutter-piece on service, and the general principles of material wear-resistant designs put forward. The sand slurry abrasion tester has been designed and developed which can simulate general dredging conditions. Summarized and presented are the position-exchange measuring method of sand slurry abrasion test and the experiment specification of sand slurry wear test of dredging conditions.
