Influence of substrate annealing on inducing Ti3+ and oxygen vacancy in TiO2 thin films deposited via RF magnetron sputtering [PDF]

, 2018
Nano-crystalline TiO2 has been prepared by RF magnetron sputtering at varied substrate temperatures ranging from 200 to 500 °C. The alteration of oxygen and titanium atom in TiO2 at uppermost surface is clearly observed on the effect of annealing ...

Residual stresses in grinding of forming tools with toric grinding pins

Procedia CIRP, 2018
The subsurface residual stress state of forming tools is an important factor for the lifetime of these tools. This is especially important for tools used in processes like sheet-bulk metal forming, where very high process loads occur in the tools during the forming operation.

Chiral Crystal Growth under Grinding

, 2008
To study the establishment of homochirality observed in the crystal growth experiment of chiral molecules from a solution under grinding, we extend the lattice gas model of crystal growth as follows. A lattice site can be occupied by a chiral molecule in

Electrochemical form grinding. Fnal report [PDF]

, 1980
Electrochemical form grinding cutting tests were performed on 25 17-4 PH stainless steel bars by a copper resin aluminum oxide wheel formed from a diamond form block. Tests investigated methods of dressing a form into a grinding wheel, nozzle design, optimum machine settings, and tolerance capabilities.

The Study on Grinding Ratio in Form Grinding with White Fused Alumina (WA) Grinding Wheels

IOP Conference Series: Materials Science and Engineering, 2018
The study is carried out based on an experiment of form grinding spur rack with white fused alumina (WA) grinding wheels. In the experiment, SOV-3020A type tri-axial image mapper is utilized to measure the profile of the tooth space in the rack, and the curve equations between the sectional area of the tooth space and the tooth sequence under different
