저탄소강의 염수분무 특성에 미치는 Cr 도금의 영향

Abstract

Most modern car may drive smoothly on various kinds of road surfaces leaving the drivers to feel pretty comfortable. Shock absorbers are the component of their cars that are assigned the task of minimizing excessive motion that the car receives due to uneven road surfaces and its environmental conditions. Automotive shock absorbers have specified chromium plating for decades because of its appearance, wear and corrosion resistance. Therefore, in this study salt water spray properties of S35C carbon steel for piston rod of automotive shock absorbers were experimentally evaluated and compared using a test specimen plated Cr and not. Although, corrosion of specimen which is not Cr plated was occured about 80% in 2 hours,corrosion of specimen Cr plated was not in 196 hours. Thus it was possible to confirm that the corrosion resistance becomes better with Cr plating.
