Abstract

Corrosion is an electrochemical reaction between metals and the environment that causes corrosion and decreases the quality of metals. Steel is a metal material that is widely applied in the industrial world. Stainless steel is stainless steel that is resistant to corrosion because it has an alloying element of at least 18% chrome and 8% nickel. To find out the superiority of stainless steel as a construction material, research on local corrosion of stainless steel needs to be done. For this reason, research on corrosion is carried out by using a 10% NaCl salt solution by varying the immersion time of stainless steel in corrosive media. From the research results it is known that the type of corrosion that occurs in specimens is the type of uniform corrosion. Likewise with the value of violence will decrease if the stainless steel is soaked longer.

Abstract

Low carbon steel metal is a type of steel that has poor corrosion resistance. For that it is necessary to protect against corrosion through a coating process. In this case the coating is carried out using solid metal and is known as cladding. In this cladding process using another metal as a coating medium, namely stainless steel, the specimen will be given additional deformation from the outside in the form of pressure and the heating process is carried out above the recrystallization temperature (950oC) then cooled slowly in free air. The heating process of the specimens was carried out with three temperature variations, namely 750oC, 850oC and 950oC with a holding time of 60 minutes, from the research results obtained that the specimens and the highest temperature, 950 oC, had better metal bonds compared to specimens at temperatures of 750 and 850oC with hardness values. average 227.96 VHN.
