Abstract

SCM415 steel for the control valve undergoes wear because of continuous movement between the valve and valve case. The wear of the valve interrupts the performance of the valve, and decreases the service life. In this study, wear characteristics of the as-received and carburized SCM415 steels are evaluated. The wear tests are conducted for various temperatures and loads using a reciprocating wear tester. From these results, wear loss, specific wear rate, and coefficient of friction are analyzed. The wear mechanism was analyzed by SEM. The interaction effects between loads and temperatures on wear loss are determined for analysis of variance using MINITAB.

컨트롤 밸브용 SCM415강은 밸브케이스와 밸브의 지속적인 운동을 통해 마멸이 발생한다. 마멸은 밸브의 성능을 저하시키고, 사용 수명을 단축시킨다. 본 논문은 컨트롤 밸브용 모재 및 침탄 처리된 SCM415강에 대하여 마멸 특성을 평가하였다. 마멸 시험은 다양한 온도 및 하중에서 왕복동 마모시험기를 이용하여 수행되었으며, 마멸량, 비마멸율 및 마찰계수를 분석하였다. 마멸 메커니즘은 SEM을 통하여 분석하였다. 마멸량에 대한 하중과 온도의 교호작용은 MINITAB을 이용한 분산분석을 수행하였다.
