Mechanical and wear optimization investigation of Titanium alloy nanocomposites made with selective laser melting process

Titanium alloys are utilized in many fields of science, engineering, and technology because of their superior mechanical and tribological properties. The investigation goal is to develop an innovative composite for use in the automobile industry by applying additive processes such as selective laser melting and reinforcing titanium alloy withbio-silica. Bio-Silica (BS) nanoparticles are extracted using agricultural waste of Calotropis gigantea as reinforcement. The Industrial Grade Titanium (IGT) alloy nanocomposites are employed for making alloys with bio-silica nanoparticles reinforcement of 0, 5, 10, and 15%. The IGT/BS nanocomposites mechanical properties, such as microhardness, tensile (ultimate and yield) strength, and compressive strength, were investigated. According to the investigation's outcomes, 15wt.%IGT/BS nanocomposites had better mechanical characteristics. L9 Taguchi's orthogonal array is utilized to illustrate the wear trials. ANOVA is used to optimize outcomes. The ANOVA was utilized to determine the ideal process parameters that would result in the lowest possible wear rate and coefficient of friction (COF). The findings indicated that the applied load of 30 N, sliding velocity of 4 m/s, and sliding distance of 2000 m may achieve the lowest wear. According to an ANOVA, load is the most significant factor (30%) influencing wear.
