On the Influences of the Finishing Condition of the Surface of Metallic Plate upon the Abrasion of Metals to the Fluid with Sand Particles

抄録

In this report, the author refers to his study on the influences of the finishing conditions of metallic plate surfaces upon the abrasion of metals to the fluid with sand particles. The working direction of file on the final finishing surface of metallic plate is set so that it has an angle of 90°to the flowing direction of the fluid with sand particles. And finishing conditions are : (1) the state of as-cast black sheet (2) bastered file finish (3) dead-smooth file finish (4) Emery paper 5 finish (5) Emery paper 3 finish (6) Emery paper 1 M finish (7) Emery paper 0/2 finish (8) Emery paper 0/4 finish (9) Emery paper 0/6 finish (10) Buff finish. Surface conditions of metallic plate just before and after the experiment of abrasion were examined with a surface tester and surface roughness was measured.
