“…Meanwhile, ceramic particles with sharp edges are easily embedded and incorporated into the metallic layer. Similar result was also observed in our previous study [30]. In this sense, spherical morphology of the SP particles benefits high deposition efficiency and low contamination.…”

“…This is a result of the low ductility, and thus, limited plastic deformation of these erosion resistant powders, at the temperatures experienced during cold spray. Several research groups have attempted to overcome this limitation of the cold spray process by premixing ductile and cermet or oxide feedstock material [9] or by making use of agglomerated powders [10]. The drawbacks associated with premixing and using agglomerated powders are reviewed in the published literature [8].…”

“…The high pressures that are generated when these particles impact the substrate cause the elongated grains to recrystallize [17,18], thus producing the finer grain structure. Several investigations have evaluated the erosion and sliding wear properties of MMCs [9,19,20] and report a substantial reduction in the erosion rate of particle reinforced MMCs over the uncoated substrate.…”

The present study reports on the erosion properties of a novel surface engineering process combining cold spray and friction stir processing. Tungsten carbide (WC-CoCr) and aluminium oxide (Al2O3) powders were cold spray co-deposited with AISI316 using a twin powder feed system. The deposited coatings were subsequently friction stir processed to refine and redistribute the reinforcing particles and remove the coating-to-substrate interface layer, thus generating a new metal matrix composite surface. Microstructural analysis of the SprayStirred (cold sprayed then friction stirred) specimens revealed significant particle refinement and improved particle distribution over the as-deposited coatings. The erosion performance of these SprayStirred surfaces was evaluated using a flowing slurry and demonstrated an 80% decrease in volume loss over the as-received AISI316 at 30° angle of attack. For SprayStirred WC-CoCr, microhardness measurements indicated an increase of approx. 530% over the unaltered AISI316 and 100% over the cold sprayed coating. These findings highlight the considerable increase in erosion performance of the SprayStirred specimens, and thus demonstrate the benefits of this innovative surface engineering process. This outcome is attributed to dispersion strengthening, imparted by the refined tungsten carbides. Furthermore, the SprayStirred WC-CoCr coating exhibited an 85% reduction in volume loss over an HVOF sprayed WC-CoCr coating

Where is the abrasive or gradual removal of materials at solid surfaces? It is caused due to the interaction between the sliding surface by mechanical action. The abrasive wears can be recognised as scratches or grooves. To enhance the wear resistance suitable nanocoating is applied on the material surface for better tribological properties such as hardness and toughness. Wear resistant nanocoating is used to reduce or eradicate wear to extend the lifetime of the EN8 steel. EN8 is unalloyed medium carbon steel with better mechanical properties than mild steel and also readily machinable in any condition. The nanocoating materials such as Al2O3, TiO2, SiC, ZrO2, WS2, Si3N4 etc., are used to reduce wear and to enhance hardness and toughness on mild steel through various nanocoating techniques. This paper deals with selection of suitable nanocoating material through AHP (Analytical hierarchal process) - a multi-criteria decision-making method.
