  • Investment Casting - an overview | ScienceDirect Topics

    So far, micro-gears, micro-turbine parts, and cast metal fibres with a diameter of 100μm and maximum aspect ratio of 90 have been successfully produced using Gold and Palladium based alloys [1,2]. Lost patterns used for such castings were produced by applying micromanufacturing technologies, in particular LIGA, laser ablation, and injection moulding.

  • Cobalt-Based Superalloys - an overview |

    The dental Vitallium (Co-27Cr-5.5Mo-2.5Ni-0.25C) alloy was one of the bases of development of cobalt-based refractory alloys for various high temperature components of the early aircrafts turbine engines in which they were extensively used, notably for vanes and even for blades (Figs. 1 and 2). The behaviors of these first cobalt alloys gave satisfactory performance under mechanical stresses in military service …

  • Precision Casting - an overview | ScienceDirect Topics

    The machining or mechanical working processes of propeller blades after casting have undergone major changes in many manufacturers’ works since the advent of numerically controlled machine tools. Early usage of automated machinery required the use of a solid pattern, which acted as the master blade from which the machine could work a new casting.

  • Nickel-Based Superalloys - an overview |

    Nickel is produced by: (1) an electrolytic method, in which the nickel-rich sulfide ore is calcined into oxide, reduced to crude nickel by carbon, and then electrolyzed to obtain pure metallic nickel; (2) a carbonylation method, in which the sulfide mineral of nickel is reacted with carbon monoxide to form nickel tetracarbonyl, which is decomposed by heating to obtain very pure metallic nickel.
