Abstract

In the present study corrosive wear resistance of NiTi coatings produced by hot isostatic pressing (HIPping) were tested using a slurry pot type of equipment. The samples were rotated in a slurry that contained 100g/l of quartz sand in liquid. Two types of liquids were used. In the corrosive test the liquid was 1N H2SO4- water solution and in the neutral reference tests the liquid was deionized water. The radial velocity was 4.7 m/s, temperature 25 +/- 5 degreesC, and duration 5 hours. Furthermore, additional corrosion tests were performed with the same apparatus and the sour liquid but without the quartz sand. The results were compared with AISI 316 steel, bulk NiTi, and some other materials. The results showed that HIPped NiTi coatings have a very good corrosive wear resistance.
