Wear Analysis of clad developed on plain carbon steel using Microwave Heating

and A-Tig Welding Process

Akshay Pathania and Sashank Thapa

Wear is the foremost problem leading to numerous replacement of engineering components in

many industries. Wear is the actual exclusion of surface material due to the frictional force between two mating surfaces. This can result in a change in component dimension which can

lead to slackness and subsequent inappropriate operation. In present work, mild steel is chosen as

a base material to improve its wear properties because it is widely acceptable material for 

engineering components. The widely acceptability of this material is due to the cheap cost, ease

machinability, deformability and weldability etc. However, the wear properties of mild steel are

very poor which leads to catastrophic failure of the component during service. Hence, it is

important to improve the surface properties of mild steel, so as it can effectively work in harsh

working environment. The surface engineering techniques refers to area which is used to

improve the surface properties of metallic and nonmetallic material and increase the working life

of the components. mong various surface modification techniques !icrowave energy cladding

and TI" cladding has been chosen to develop the clad and analysis of wear performance between

these two techniques has been shown.

• The main ob#ective of the present research is to develop a new cost effective as well as

green technique for producing coatings$claddings of metal%based materials using a non%

conventional source of energy &microwave' which offer variety of advantages while

compared to the conventional processes.

• To improve the mechanical and metallurgical properties of the most used engineering

material in industries.

• The microwave clads showed good metallurgical bonding with substrate by partial

mutual diffusion of elements.• The wear resistance of microwave processed clad has been increased by almost (() times

of mild steel at *.+ g and *.+ m$s.

• The microwave cladding has been successfully carried out on -)) W at (.+ "H/ at 01)

seconds on domestic microwave oven.
