Abstract
Metals and alloys can undergo intergranular corrosion attack, wear and ultimately can result in failure under various service conditions. To reduce this possibility of failure by different modes, metals and alloys are employed with certain surface treatment processes. Out of numerous surface treatment processes available today cladding has evolved itself as one of the noble techniques in this era to provide and act as a protective layer that enables the component or specimen to withstand and enhance the service life under extreme conditions. There is a various additive method of cladding who found to be economical and efficient over the perspective of providing a good metallurgical bond with the least possible dilution of the base material. This study tries to figure out the possibilities concerning conventional and unconventional cladding techniques based on processing techniques, metallurgical bonding, advantages associated, and limitations as attached to it.
Highlights
The current study tries to focus on a unique study in surface treatment methods in the context of various cladding techniques with strong metallurgical bonding and minimal substrate dilution
Stainless steel (SS) bears good mechanical properties but it has no electrical and thermal conductivity so a coating can be a pragmatic solution to such problems as it can compensate for these deficiencies. [2]
The cladding process is characterized by excellent metallurgical bonding with the little dilution of the base material
Summary
The current study tries to focus on a unique study in surface treatment methods in the context of various cladding techniques with strong metallurgical bonding and minimal substrate dilution. A coating is a widely used surface treatment method that involves applying a layer of appropriate materials to substrates with desired qualities. Cladding is a typical surface modification/treatment technique that involves partial melting of the substrate and complete melting of externally supplied powders onto the substrate to develop and encapsulate the dominating and prevailing characteristics of appropriate materials on surfaces of desired thickness. A small fragmented zone of the substrate material melts during the cladding process, forming a strong metallurgical connection with the molten wear-resistant material, which is usually encapsulated as powder. The metal used must be ablation-resistant.[4]
