摘要

The focus of this project is on the effect of dynamic solidification in a high-chromium white cast iron containing 17% Cr, with titanium added as a primary carbide-forming element for comparison with static solidification. Titanium additions range from 0%, 0.8%, 1%, to 2.5%, aiming to achieve a microstructural modification of the base alloy, specifically through the formation of titanium carbides. The purpose of this modification is to improve the alloy’s wear resistance against abrasion. The operating conditions during the wear test were as follows: a load of 94 N, a sliding distance of 1500 m, silica sand as the abrasive element, a granular flow rate of 300 g/min, and a 22 cm diameter rubber wheel rotating at 200 rpm. In this study, the abrasive wear rate was reduced by up to 25.43% in the alloys containing 2.5% Ti compared to those with 0% Ti, under dynamic solidification conditions.
