“…The hybrid MH approach was used by the research group to modify the surface layer of metallic material by suitable overlaying material. Afterwards, many researchers utilised this technique to enhance the tribological and mechanical properties of the different metal-based substrates by depositing clad material of superior properties onto them [16][17][18][19][20][21][22][23][24][25][26][27][28]. Ni and Co based claddings were widely used for tribological applications.…”

In this present study, the Inconel-625 powder was used for the surface modification of SS-304 alloy by utilizing the concept of a hybrid microwave heating technique. The XRD analysis shows the presence of various carbide and Laves phases in addition to a Ni-Cr-Fe-based face-centred-cubic matrix in the modified clad layer. The microstructural analysis revealed that the developed clad was metallurgically bonded with the substrate and free from any interfacial cracks. The modified layer mainly consists of two regions: cellular (matrix) regions and grain boundaries (GBs) regions. The average porosity in the modified clad layer was evaluated to be about 1.65%. The average microhardness (440±45 HV) of the modified clad layer was observed to be about 2.1 times the base metal microhardness (210±10 HV). The clad specimens exhibited a considerably lower wear rate (about 2.8 times less weight loss) than the substrate SS-304 during the dry sliding wear test. The shallow grooves, craters, and material debonding were the typical fracture features associated with the clad surfaces during rubbing when examined under a scanning electron machine apparatus.

“…Material processing through microwave energy is emerging as a new technique to fabricate alloy material and to improve the tribological properties of the material [2]. Several experiments are carried out for processing of materials through microwave energy such as sintering, joining of materials and manufacturing of alloys to overcome the limitations of the surface-related problems [3]. The desire for more strength and hard material is a major requirement in the present industries along with the enhanced mechanical, physical and chemical properties to improve wear and corrosion resistance properties.…”

In the present work, clads were developed through microwave energy which is as an emerging trend. Martensitic stainless steel (SS-420) is considered as a substrate material to improve its surface properties. In the present work, clad powder such as tungsten carbide and cobalt-based powders were used in the weight ratio of 1:0.12, respectively. The clads were developed using domestic microwave oven at 2.45 GHz frequency and 900 W power through microwave hybrid heating technique. After performing a number of trials, the clads were developed with good metallurgical bond with an exposure time of 30 min. The main objective of clad development is to obtain a good mechanical and tribological properties. Wear studies through pin-on-disc method of the developed clad was performed on the basis of Taguchi method (L9) orthogonal array. The main influencing factors considered are sliding distance, sliding speed and load. It is observed that the sliding distance is most dominating factor than load and sliding speed.

“…This crack free structure leads to perform developed mechanical properties of material surface which is under analysis. It was discovered that the enhancement of clad surface through microwave energy has immense impact on material development cost and also involves minimal time and energy [16][17][18].…”

Abstract. Small and large scale (gas power plant, hydro power plant), automobile industries are suffering by failure of component. Sometimes, it is also observed that the component which was failed due to these reasons are very much costly and replacement of those also very difficult due to the complex geometry. By using Microwave hybrid heating, WC-12Co based clads were developed on austenitic stainless steel (SS304). Microwave clads were developed by introducing the preplaced, preheated powder for a duration of 15 min to microwave radiation at 2.45GHz frequency and 900 W power in domestic microwave applicator. By using optical microscope and scanning electron microscope (SEM), the developed clads were characterized. By using pin-on-disk, wear performance of the WC-12Co based clads and unclad samples were tested. It is observed that developed clad samples performed superior wear resistance than unclad samples.
