Titanium alloys of which the strength ratios are higher than those of steels, are respected for the materials of deep water riser. One of the problems applying titanium alloys to riser is how to estimate their erosion characteristics in mud water containing barite.<BR>In this study, we made erosion test equipment which modeled the fundamental part of actual riser. Using the test equipment, effects of the composition of mud water and flow rate of mud water on erosion damage for titanium alloy with and without surface modification treatment, were discussed.<BR>The results of the erosion test showed that the erosion damage of titanium alloy decreased to less than 1/20 of steel. It was found that the titanium alloy possessed good erosion resistant characteristics, and surface modification treatment was not necessary.
