Thermal plasma spraying method was used for coating the pre-prepared surfaces of turbine blades. Nickel (Ni) as a base material with fixed percentage alumina (5%Al2O3), and (5,10,15,20,25%) Boron carbide (B4C) reinforcement material. Cermet powders were mixed one hour, then bases steel type (316L) prepared roughened using sandblasting to increase adhesion strength between coated materials base....

In this study, nanoparticle zinc ferrites with different particle sizes were synthesized via sol-gel method using ferric nitrate and zinc nitrate. The obtained gel was dried and calcined at three different temperatures (i.e. 500, 600 and 800 °C) for 2 h. Adequate amounts of the as-synthesized nanoparticle samples were then added to the mixture of polyester resin and formaldehyde resin. The ...

A black mask (BM) is a layer used to improve the display quality by suppressing light leakage. In general, the BM is formed by a photolithography process. In this study, a novel technique for the fabrication of a quasi-black mask (q-BM) is proposed; the q-BM was composed of vertical and hybrid orientation areas, patterned by a separation coating technique using an electro-spray deposition metho...
