Abstract

The increasingly widespread use of structural steel in everyday life, despite its tendency to undergo corrosion, results in financial losses and poses safety risks if damage occurs. This study aims to analyze the effects of nitrocarburizing on the hardness, corrosion rate, microstructure, and composition of low-carbon materials SS400 and ASTM A36. The research method used is experimental. Data analysis techniques were obtained by comparing the results of each test. The nitrocarburizing test results showed differences in hardness values and corrosion rates for SS400 and ASTM A36. The SS400 test results at 350°C were 221.04 VHN and 0.26993 mpy, at 400°C were 278.85 VHN and 0.30959 mpy, and at 450°C were 440.39 VHN and 1.4548 mpy. The ASTM A36 test results at 350°C were 377.43 VHN and 0.43071 mpy, at 400°C were 399.58 VHN and 0.085371 mpy, and at 450°C were 230.83 VHN and 1.4336 mpy.

Abstract

Natural fiber composites are increasingly being developed to substitute less environmentally friendly materials such as metal and fiberglass. Petung bamboo has the potential to be a substitute for glass fiber in polymer composite reinforcement because it has good fiber quality. This research aims to determine the effect of random fiber arrangement with variations in fiber length on mechanical strength. The composite was made using the hand lay-up method with fiber length variations of 5 mm, 10 mm, 15 mm, and 20 mm. The volume fraction of petung bamboo fiber is 30% soaked in 5% NaOH for 2 hours. The research results show that specimen C has the highest tensile strength and elastic modulus values ​​of 1.25 Kgf/mm^2 and 1.93 Kgf/mm^2. In contrast, specimen A has the lowest tensile strength and elastic modulus values ​​of 0.76 Kgf/mm ^2 and 1.14 Kgf/mm^2. The rich, void, and fiber pull-out matrix causes the mechanical strength of the composite to be less than optimal. The effect of adding petung bamboo fiber in the composite can increase the mechanical strength as the fiber length increases.
