The majority of the properties required for orthopedic implant operation are demonstrated by magnesium and its alloys, however, the metal degrades rapidly in the body's environment. Therefore, a magnesium-based metal matrix composite capable of safely and gradually degrading in the body within the required healing time is required, thereby eliminating the need for a second surgery. The degradability of this newly formed alloy was done via corrosion test of this alloy in various corrosive media namely, H20, NaCl, Urine, Blood, and Plasma. Three samples A (50% reinforcement), B (25% reinforcement), and C (No reinforcement) of grade AZ31B Magnesium alloy and Calcium Carbonate powder reinforcement were developed via stir-casting technique. The impact strength of this alloy was carried out by using Charpy Impact Tester, while the microstructural characterization was determined by Scanning Electron Microscope (SEM).

WC-12%Co, Cr 3 C 2 -25%NiCr, 80%Ni-20%Cr, 87%Al 2 O 3 -13%TiO 2 coatings were deposited by Air Plasma Spray (APS) technique on ASTM A36 steel. Erosion behaviour of sprayed coated samples were investigated at three different impact angles (45°, 60°and 90°). The mechanism of erosion was investigated on uncoated and coated samples. The rate of erosion of the substrate first increased with increasing angle of impact and then gradually decreased. But the erosion rate of the coated samples increased steadily. Substrate shows the higher metal removal whereas coating shows the higher erosion resistance. WC-12%Co coated samples performed well in erosion testing and offered best erosion resistance as compared to the substrate and all other coatings. Ductile fracture takes place on substrate material at higher impact angle. Overall, all the coated samples have shown less erosion propensity when compare to the bare one.

“…Optical Microscopy(OM) was used to examine the microstructural evolution and the grain sizes of the processed samples. A mircohardness tester were used to conduct the Vickers microhardness with standard in line with ASTM E92-82 (Wu et al 2015), dwell time and load are 15 seconds and 300KN respectively. Instron tensile machine was used for the tensile tests with 2.0×10−3 s−1 strain rate.…”

In this study, metal matrix composite is fabricated on 1100 Aluminium alloy by multi pass friction stir processing using different reinforcement particles namely Fly Ash, Palm Kernel Shell Ash, Ti62222 and 304 Stainless steel. Metal matrix composites with average grain size of 6.5 μm are achieved. The addition of reinforcements at the stir zone has enhanced the mechanical properties of the 1100 Al alloy, finer grain structure is also evident after three cumulative passes. Higher strength ranging from 268 to 454 MPa is achieved. Microhadrness of the developed metal matrix composites reinforced with various particles exhibits an improved average microhardness values that ranges from 75 to 95 HV. 304 stainless steel serves as the best reinforcement to be used, offering higher hardness values and good tensile strength of 454.18MPa. The sets of new alloys fabricated in this study can be considered for typical surface engineering applications
