Abstract

As a component which hold complex load, gear needs a special heat treatment. This heat treatment should produce the high hardness value of material surface in order to hold the friction load and left the soft and tough characteristic in it’s core for holding the bending load. The heat treatment which can produce those characteristic is called the surface treatment. One of the surface treatment that has been done on the gear is aluminizing. Aluminizing is not only increase the surface hardness, but also increases the defense corrosion of the metal surface. In this research, the aluminizing was done by the methods to pour a liquid alumunium on the lower cylinder carbon steel surface which have varied the roughness surface grinded with abrasive paper until grid 800, 1500 and 2000 until sticky . And it was continued by the temperature heating of 700 0C with two hour holding time. This alumunium diffusion method increases the surface hardness up to 1287,8 HVN, while in the core hardness decreases into 127 HVN. From this micrographic test, we can conclude that aluminizing with Hot Dip Aluminizing method and grinded with abrasive paper until grid 800 continued by heating of 700 0C produced more uniform diffusion layer, great case depth, and less porosity as the result of the oxidation of aluminizing with pouring a liquid alumunium on the lower carbon steel surface.
