With the use of this machine, the experiment was conducted on SS 400, SUS 430 F, SUS 304 and SUS 403 test specimens. The following results were obtained. (1) The improved sand erosion testing machine has an operational temperature range from 293K to 343K with a temperature variation of ±0.5K. Also, it has an operational slurry speed range from 5.5 mls to 10.5 mls with a speed variation of about 0.2 %. This is very favorable in the study of temperature dependence and slurry speed dependence in sand erosion behavior. (2) The order of sand erosion resistance for SS 400, SUS 430 F, SUS 403 and SUS 304 does not vary whichever temperature and whichever slurry speed is used. (3) The sand erosion behavior is highly dependent on slurry temperature and slurry speed. (4) In the development of sand-erosion resistant materials, materials with high hardness and good corrosion resistance was deduced to be advantageous.}, pages = {63--72}, title = {改良型サンド・エロージョン試験機の試作}, year = {1996} }
