Evaluation of bond quality for stainless steel-Carbon steel friction surfaced deposits.

Friction surfacing is one of the advanced techniques in the family of friction welding processes and is used for deposition of desired material on substrate of interest. These deposits are of solid phase bonding. No external heat source is required and heat is developed by friction. It is suitable for critical applications such as wear resistance, corrosion resistance and also for challenging dissimilar applications. In this work, friction surfacing was carried out by using Stainless steel as mechatrode and Low carbon steel as substrate. This paper is an attempt to give review details of the variants of friction surfacing techniques, bonding mechanism, factors selection of process parameters to apply on different combinations of materials and confirming the same with experimental test results. Effect of process parameters on the responses like width, height, surface roughness, tensile strength shear strength and ratio of tensile strength and shear strength are discussed in details. Testing of deposits for quality evaluation also carried out such as visual inspection, adhesion test, and microstructure and hardness distribution to find potential industrial applications. For the particular combination, the influence of the factors which are effecting above responses was discussed and regression equations were arrived at based on the design of the experiments approach. It is hoped that this research report will be of immense useful for all professional who would like to exploit this process development and identifying the useful applications. (C) 2015 Elsevier Ltd.
