Optimization of Leaching Parameters for Recovery of Tantalum from Waste Tantalum Capacitors

Cutting Performance and Tool Wear of AlCrN- and TiAlN-Coated Carbide Tools during Milling of Tantalum–Tungsten Alloy

“…As the cutting speed increases, the work-hardening effect intensifies, resulting in enhanced material strength and reduced plasticity, which in turn causes a rapid increase in the cutting forces and an improvement in surface roughness. (2). When machining tantalum-tungsten alloy Ta-2.5W, the superior hardness and exceptional wear resistance of AlCrN coatings stabilize the cutting edge more effectively than TiAlN-coated tools; this results in a reduction in cutting forces by 1% to 15% and a decrease in surface roughness by 6% to 20%.…”

“…With the development of manufacturing industries, tantalum-tungsten alloys have gained popularity due to their high strength, high melting point, good ductility, corrosion resistance, wear resistance, and high-temperature mechanical properties [1]. In recent years, they have been widely used in the field of electronics, the chemical industry, aerospace, national defense, the military industry, biomedicine, etc., as a material for parts such as aviation engines, gas turbines, weapons and equipment, and human sponge bones [2][3][4][5]. However, due to their good plasticity and high strain-hardening capacity, they cause problems such as large cutting forces, elevated temperatures, and poor chip breaking [6,7].…”
