New Evolve of Plasma Alloying on Titanium Alloys Surface

Zhang Gaohui,Xu Zhong,Zhang Pingze,Ge Hongliang,Cui Yujian,Wen Tingdun,Pan Junde

Strategic Study of CAE 2007, Volume 9, Issue 11,   Pages 163-166

Abstract:

Aimed at improving wear, corrosion resistance and enhancing fire retardance, several plasma surface treating methods on titanium alloys had been presented, which included add-arc glow hydrogen-free carburizing plasma depositing on titanium alloy, double glow plasma hydrogen-free carburizing on titanium alloy, double glow Mo diffusing,  double glow Cr diffusing, double glow Cu diffusing. The results showed that gradient layer had formed on the titanium alloys surface, that was of great significance on wear, corrosion resistance and fire burning resistance.

Solvent-resistant porous membranes using poly(ether−ether ketone): preparation and application

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1536-1559 doi: 10.1007/s11705-022-2221-8

Abstract: Poly(ether−ether ketone) (PEEK) is a linear aromatic macromolecule, which can form semi-crystalline aggregative status, allowing PEEK materials to have strong environment tolerance and excellent physicochemical properties. PEEK materials have become a promising alternative to fabricate particular membranes used in extreme conditions. In the past few decades, many researches and evolutions have emerged in membrane fabrication with PEEK materials and its applications for treating organic solvents and their mixtures; however, there are little systematic and comprehensive literature to summarize fabrication approaches, compile applications, and elaborate PEEK property-structure relationship. In this review, the main approaches to fabricate PEEK-based membranes are illustrated concretely, including conventional thermal-induced and non-solvent-induced phase separation, and novel chemical-induced crystallization; the representative applications in ultrafiltration, nanofiltration and membrane contactor containing organic solvents are demonstrated systematically. Meanwhile, the mechanism to tune PEEK solubility in solvents, which can be achieved by altering monomers in synthesis processes or changing membrane preparation routes, is deeply analyzed. Moreover, the existing problems and the future prospects are also discussed. This review provides positive guidance for designing and fabricating membranes using PEEK and its derivative materials for task-specific applications in harsh conditions.
