Abstract

Boronizing is a thermo-chemical surface hardening treatment in which boron atoms diffused into the metal substrate to form metallic boride layer, providing high hardness, corrosion resistance, and 3-10 times increasing service life. This type of surface treatment is widely used in many applications. The purpose of this work is to study and to investigation the hardness of the part before and after the boronizing treatment. The types of steel that was choose in this study is Stainless Steel AISI 316 (austenitic type). The boronizing powder pack that are used is Ekabor 1. The pack boronizing process involves the embedding of the metal into boronizing powder mixture. The unboronized and boronized of specimens at different value of powder condition will be analyzed in term of their hardness and other abilities using Rockwell Hardness testing apparatus. Different in hardness values for each specimen that was boronized at various conditions will be further analyzed to verify the effects of boronizing powder condition on hardness. The microstructure of boronized and unboronized specimens observed in this study. All of the causes were discussed.
