As an effective surface modification technique, micro-arc oxidation (MAO) is now widely used to improve the hardness and wear resistance of Ti and its alloys by low-cost and thick ceramic coatings. In this study, MoSi2 – modified ceramic coatings were deposited on Ti–6Al–4V alloy (340 HV) by MAO using an aqueous solution of (Na2SiO3),(NaPO3)6 and (NaOH) and MoSi2 particles. MoSi2 particles (3, 5,...
Przedstawiono wyniki badań mikrotwardości trzech powszechnie stosowanych kompozytów handlowych typu bulk-fill. Celem pracy była ocena wpływu fotopolimeryzacji próbek o grubości nominalnej 2 mm na wytrzymałość stykową powierzchni. Wytrzymałość stykową oceniano w testach mikrotwardości metodą Vickersa. Badano mikrotwardość na powierzchniach naświetlanej (LC) i nienaświetlanej (NLC) lampą stomatologiczną...
Recently, dissimilar metals have found applications in the process of resistance spot welding (RSW), particularly within the electric vehicle industry. Notably, copper and aluminum have gained significant importance in these sectors due to their advantageous characteristics for the industry requirements. The mechanical behavior of these materials is essential to maintaining structural integrity. The...
