Utilization of Groundnut Shell as Reinforcement in Development of Aluminum Based Composite to Reduce Environment Pollution: a review

Metal Matrix composite is a metal reinforced with two or more constituents which can be any other materials either metal or non-metal. Metal matrix composites (MMCs), which are inherently intelligent, are lightweight and high-performance, ever-expanding materials. The structural and functional properties of these materials may be modified by industrial requirements. Researchers and the industry are attracted by the process technology used in the production and processing of these products. The hybrid-electric discharge process for MMCs is a promising and the most effective nonconventional process. It has greater expertise in manufacturing complex shapes with greater precision. This paper gives an updated analysis of the development and advantages of various routes for composite manufacturing and machining. It reports on several realistic analyzes and study results, including various manufacturing and processing problems for MMC Since the last few years, hybrid electrical discharge machining has been an active field of research in critical and nonconventional machining. This paper includes annual research in production, traditional machining, unconventional machining, and hybrid MMC machining. The final part of the paper addresses conclusions and future scope.

This paper presents an overview of the modern advancement of micromilling as pertained to the machining process from recent research and advancement perspective. The review starts by displaying the characteristics and micromilling contributions background, and later sets up the reader to difficult-to-cut materials. However, the fabricating process usually becomes complicated owing to these material's unique metallurgical properties. This paper brings to focus the micromilling of difficult-to-cut materials, especially materials that are currently the highlights of various industries. The discussion of research and attributes of difficult-to-cut materials are covered in further detail, which serves with opportunities for future developments.

“…In the body, these materials stimulate tissue production to cover and protect the prothesis 14) . Several types of bio inert ceramics that can be used are titanium dioxide (TiO2), zinc oxide (ZnO), hydroxyapatite (HA) and zirconium dioxide (ZrO2) 15,16) .…”

CoCr alloy is mostly used as biomaterial implant. However, it still has several weaknesses. Therefore, it is necessary to modify the surface to improve its biocompability. This research is a preliminary study on CoCr coated with Hydroxyapatite (HA)/Zirconium Dioxide (ZrO2) using Thermal Flame Spray method. 5 % -20 % ZrO2 was mixed with HA. Besides improving the biocompatibility, ZrO2 is believed to be able to enhance the antibacterial properties. Characterization test was performed using FE-SEM. The coating was analyzed for corrosion rate, surface roughness and antibacterial activity. Adding ZrO2 to HA has been proven to be able to improve corrosion rate. Combination of 80HA-20ZrO2 is the most effective bioceramic mixture, producing lowest corrosion rate of 0.213 mm/year in HBSS media. This is due to the increased reactivity value and better passivation reaction than CoCr without coating. Antibacterial activity test revealed that the coating could form inhibitory area around the sample meaning that the coating can provide bacterial resistance for the implant.
