Investigations of Ti Binary Alloys Manufactured by Powder Metallurgy for Biomaterial Applications

Abstract

Biomaterials encompass synthetic alternatives to the native materials found in our body. They have shown rapid growth in the field of elderly population demands with the prolongation of human life. Titanium is one of the biomaterials with excellent properties and biocompatibility. However, its high stiffness may cause weakening in the structures. To sort out this problem, Ti-Cr, Ti-Mo, and Ti-Cu alloys were produced by powder metallurgy. Metal powders were mixed by mechanical alloying. After pressing and sintering, characterizations were carried out by scanning electron microscopy, X-ray diffraction, electron backscattering diffraction, and three points bending test.

“…Higher compaction pressure was used because the hardness of the MA particles increased due to plastic deformation after milling, so reducing the obtained porosities is desirable. Sintering was carried out in a Carbolite HVT 15/75/450 tubular furnace at high vacuum (<10 -4 mbars) with a sintering cycle of 950 °C for 3 h to obtain rectangular samples measuring 12x30x5 mm 3 with optimized sintering parameters from previous studies to ensure better alloy sintering (Amigó et al, 2019;Atay et al, 2018;Mohan et al, 2017).…”
