Control of intermetallic compound layers at interface between steel and aluminum by diffusion-treatment. Microhardness values of coatings on L stainless steel as intermetalicox function of temperature for the indicated pressure and seconds of reaction. Finally, Si is concentrated inside the interface of reaction but in homogeneous concentration around the intermetallic phases.
Pdf converter convert files to and from pdfs free online. The aluminides generally are applied on steel surfaces for applications in the electric power industry, petrochemical industry and other energy conversion systems due to their low cost and excellent performance Kobayashi and Yakou, ; Chang et al. Friction stir diffusion bonding of dissimilar metals. The use of intermetallic compounds has emerged as an important alternative, given the high hardness and high thermal stability that many of these compounds pose.
Compression intefmetalicos performed using two bars of the molybdenum TZM alloy.
According to the calculated values and the activation energy for the diffusion coefficients of Fe and Mn in aluminum, the speed at which these compuesyos diffuse through the layer of products is very similar. Inclusions may also have previously existed on the surface of the steel sheet; these particles were then trapped due to the speed at which the interface was formed.
Subsequently, the growth of the alloy layer and quaternary intermetallic formation in the coating is a function of temperature and processing time.

Microhardness testing was performed in a Vickers hardness tester, using loads of 50 g, as it will be discussed later. Under these conditions, the reaction zone between the substrate and coating is more compacted and well-adhered, with a microhardness of Vickers. The dark grey phase, marked with the number 1 in Fig. In addition, this figure shows the compueztos of all elements in the interface and an even greater penetration of Al and Si into the substrate.
