... their deposition. The XRD spectra revealed that matrix and reinforcements are dominant phases in the clad layer. The formation of compounds reflected considerably a lower dilution of reinforcement phase with Ti6Al4V matrix during melting and deposition. Higher the microhardness of the (Al 2 O 3 + TiN)/Ti6Al4V clad...

... and subsurface layers. This work addresses the influence of selected deep rolling parameters (pressure, speed, feed, and number of passes) on the surface integrity (roughness, surface and subsurface microhardness, and microstructure) of AISI 1020, AISI 1065, and AISI 1080 carbon steels. Deep rolling...

... and wear properties of ZrB 2 -containing composite coating sliding against a GCr15 steel ball at different normal loads and sliding speeds were evaluated. The morphologies of the worn surfaces were analyzed by means of SEM and three dimensional noncontact surface mapping. It is shown that the microhardness...

... with oxidation or hot corrosion resistance, is required. In the present work, NiCrAlY and Ni - 20 Cr metallic coatings were deposited on an iron-based superalloy by a shrouded plasma spray process. The coatings were characterized by scanning electron microscopy, optical microscopy, microhardness testing, and x...
