Recent process developments have permitted the highly anisotropic bulk micromachining of titanium microelectromechanical systems (MEMS). By using the metal anisotropic reactive ion etching with oxidation (MARIO) process, arbitrarily high-aspect-ratio structures with straight sidewalls and micrometre-scale features have been bulk micromachined into titanium substrates of various thicknesses, ran...

To evaluate the significance of thin-film composite membrane surface morphology on water productivity, flat-sheet experiments were conducted with silicon dioxide, titanium dioxide, and cerium dioxide nanoparticles. The polyamide thin-film active layer exhibited a valley and ridge morphology that was directly related to the surface roughness, and was found to contribute to particle accumulation ...

Laser beam welding produces good quality welds with minimum shrinkage for sheet metal joints. The quality of welded joint depends upon surface morphology, hardness, mixing of liquid phases and metallurgical non-homogeneity induced by gradients of temperatures and cooling rate at the weld interface. In the present investigation, Titanium Grade5 (Ti) and AA2024 (Al) alloy dissimilar sheet metals ...

in this work, the strength of cold roll bond of the commercially pure titanium (cp ti) sheet and the effect of tio2 nanoparticles on bond strength was investigated. through the accumulative roll bonding process, which is considered among the important severe plastic deformation processes, the creation of suitable bonds plays a significance role in the ultimate strength of the bond. thus, resear...

TiO(2) is one of the most studied compounds in materials science. Owing to some outstanding properties it is used for instance in photocatalysis, dye-sensitized solar cells, and biomedical devices. In 1999, first reports showed the feasibility to grow highly ordered arrays of TiO(2) nanotubes by a simple but optimized electrochemical anodization of a titanium metal sheet. This finding stimulate...
