PY - 2015 DA - 2015/03/23 TI - Structure and Microhardness of Titanium-Based Coatings Formed by Multichamber Detonation Sprayer SP - 532825 VL - 2015 AB - A series of titanium-based coatings (50–550 μm thick) on an aluminium substrate was deposited via multichamber detonation sprayer with different barrel lengths (300, 400, and 500, all in mm). The titanium-based coatings obtained in these three experiments were examined by optical microscopy, scanning electron microscopy, and X-ray phase analysis. The hardness tests were carried out by the Vickers method with a test load of 50 g. The multichamber detonation sprayer with a barrel length of 500 mm produced the dense layers of coating with hardness of 1300±250 HV0.05 and porosity of 0.24%, the best result in the experiments.
