Optimization of the chemical milling of investment cast titanium alloys
Investment casting is a popular casting technique for manufacturing of several titanium alloy components dedicated to different industrial applications, as aerospace and automotive. This manufacturing process could be an economic net-shape technology, since the investment casting allows obtaining complex shapes, accurate geometries and reduced thicknesses. However, the reactions between titaniu...
متن کاملTitanium Alloys
Although originally discovered in the 18th century [1], the titanium industry did not experience any significant advancement until the middle of the 20th century through the development of the gas turbine engine [2]. Since then, the aerospace sector has dominated worldwide titanium use with applications in both engines and airframe structures [3]. The highly desirable combination of properties,...
متن کاملA Novel Surface Treatment for Titanium Alloys
High-speed commercial aircraft require a surface treatment for titanium (Ti) alloy that is both environmentally safe and durable under the conditions of supersonic flight. A number of pretreatment procedures for Ti alloy requiring multi-stages have been developed to produce a stable surface. Among the stages are, degreasing, mechanical abrasion, chemical etching, and electrochemical anodizing. ...
متن کاملCryogenic Milling of Titanium Powder
Ti Grade 2 was prepared by cryogenic attritor milling in liquid nitrogen and liquid argon. Two types of milling balls were used—stainless steel balls and heavy tungsten carbide balls. The effect of processing parameters on particle size and morphology, contamination of powder and its microhardness was investigated. Milling in liquid nitrogen was not feasible due to excessive contamination by ni...
