![]() ![]() SEM and 3D morphology test results demonstrated that the coating’s wear mechanism changed from adhesive wear and abrasive wear to fatigue wear and abrasive wear with the increase in Ti content. High entropy means the data has high variance and thus contains a lot of information and/or noise. Entropy is just a way of expressing the number of states of a system. The coating’s wear resistance was the best when the molar ratio of Ti was 0.75, the friction coefficient was 0.296, and the wear amount was 0.001 g. Entropy has many interpretations such as 'measurement of order' or 'measurement of information', but instead of looking at the interpretations you could just look at what it actually is. The friction and wear findings demonstrated that the addition of Ti can substantially reduce the coating’s friction coefficient and wear rate. In equations, entropy is usually denoted by the letter S and has units of joules per kelvin (JK 1) or kgm 2 s 2 K 1. It is an extensive property of a thermodynamic system, which means its value changes depending on the amount of matter that is present. The hardness test findings showed that when the molar ratio of Ti was 0.75, the coating’s microhardness was 511 HV0.5, which was 1.9 times the hardness of the 40Cr (256 HV0.5) substrate and 1.46 times the hardness of the CrCrFeMnNi HEA coating (348 HV0.5). High-entropy alloys have become one of the most promising medical metal materials in recent years due to their biological safety, high strength, high corrosion. Entropy is the measure of the disorder of a system. Ti addition can effectively enhance the coating’s mechanical properties. As a consequence, a high zT value (1.8 at 900 K, n-type) and conversion efficiency (12.3 at T 507 K) in the high-entropy material and module were realized in the experiments. The EDS findings indicated that Cr and Co/Ni/Ti were primarily enriched in the dendrite and interdendrite, respectively. Fe 2Ti, Ni 3Ti, and Co 2Ti intermetallic compounds were discovered in the coatings when the molar ratio of Ti content was greater than 0.5. The findings demonstrated that the CoCrFeMnNiTi x HEA coatings formed a single FCC phase. International Conference on Recent Advances in High-Entropy Alloys scheduled on February 25-26, 2023 at Tokyo, Japan is for the researchers, scientists, scholars, engineers, academic, scientific and university practitioners to present research activities that might want to attend events, meetings, seminars, congresses, workshops, summit, and symposiums. X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) were used to characterize the phase composition, microstructure, and chemical composition of the samples. To enhance the friction and wear properties of 40Cr steel’s surface, CoCrFeMnNi high-entropy alloy (HEA) coatings with various Ti contents were prepared using laser cladding. ![]()
