Abstract

Iron surface hardening technology is done with a particular technique to minimize oxygen in order to avoid the formation of oxide compounds that can inhibit the diffusion process and reduce the reactivity between the iron and the reinforcement material. Conventionally, this technique is done by creating an inert gas conditions using argon gas flow, or it can also be done by creating a system under vacuum conditions during heating. This technique is operationally costly because it must provide argon gas or vacuum machines are expensive. This study is intended to reduce the magnitude of these costs using the new methods with less operational costs. In this study, iron surface hardening process conducted by using mechanical pressure and heating without vacuum or argon gas flow. Samples iron S45C to be hardened is placed in a container shaped cylindrical tube made of 304 stainless steel and covered with a powder mixture consisting of 5% boron carbide (B4C), 90% of silicon carbide (SiC), and 5% potassium boron fluoride (KBF4) under certain pressure. Samples were prepared is heated at a temperature of 700, 800, and 900oC with heating time for 8 hours. Layer formed on the metal surface can be identified as a layer of iron borides I (FeB) on the surface and a layer of iron borides II (Fe2B) at certain depths. From the micro hardness test results using Vikers identor expected to obtain micro hardness value is greater than the base sample so it can be used as a raw material component machining.
