Etch characteristics of KOH, TMAH and dual doped TMAH …

KOH (potassium hydroxide) is a non-toxic, economical and commonly used alkali metal hydroxide silicon etchant which requires simple etch setup and provides high silicon etch rate, high degree of anisotropy, moderate Si/SiO 2 etch rate ratio and low etched surface roughness [1], [2]. But KOH damages exposed aluminum metal lines very quickly and ...

Corrosion Resistance of Titanium Alloys Anodized in …

Titanium alloys present superior electrochemical properties due to the generation of the TiO2 passive layer. The ability to generate an oxide passive layer depends on the anodized alloy. This work mainly studies the corrosion resistance of the alloys Ti-6Al-2Sn-4Zr-2Mo and Ti-6Al-4V anodized in NaOH and KOH at 1 M and 0.025 A/cm2 of current density. The …

The addition of the KOH group on the pure titanium (T) or bioactive glass (TEOS) surfaces generated a tendency for better results for mineralization. Groups covered with bioactive glass (TEOS, TEOS + KOH) tended to outperform even groups with titanium substrate (T, T + KOH). The addition of both, bioactive glass and KOH, in a single pure ...

Oxidation Behavior of Titanium Boride at Elevated Temperatures

The oxidation behavior of dense TiB 2 specimens was investigated. Hot-pressed TiB 2 with 2.5 wt% Si 3 N 4 as a sintering aid was exposed to air at temperatures between 800° and 1200°C for up to 10 h. The TiB 2 exhibited two distinct oxidation behaviors depending on the temperature. At temperatures below 1000°C, parabolic weight gains were observed as a result …
