“…This determines areas of application of Ni-Cu alloys. They are widely used for manufacturing various components of equipment in chemical, oil and marine industries (such as drill collars, pumps, valves, fixtures, piping, fasteners, screws, propeller shafts, steam generators, turbines [22][23][24][25][26][27]), for protective coating [28,29], for manufacturing electrical and electronic equipment (resistors, bimetal contacts, capsules for transistors and ceramic-to-metal sealing [30,31]), and in fuel cells [32,33].…”

Nickel-Copper (Ni-Cu) alloys exhibit simultaneously high strength and toughness, excellent corrosion resistance, and may show good wear resistance. Therefore, they are widely used in the chemical, oil, and marine industries for manufacturing of various components of equipment, such as: drill collars, pumps, valves, impellers, fixtures, pipes, and, particularly, propeller shafts of marine vessels. Processing technology includes bar forging, plate and tube rolling, wire drawing followed by heat treatment (for certain alloy compositions). Growing demand for properties improvement at a reduced cost initiate developments of new alloy chemistries and processing technologies, which require a revision of the microstructure-properties relationship. This work is dedicate to analysis of publicly available data for the microstructure, mechanical properties and strengthening mechanisms in Ni-Cu alloys. The effects of composition (Ti, Al, Mn, Cr, Mo, Co contents) and heat treatment on grain refinement, solid solution, precipitation strengthening, and work hardening are discussed.

In this study, Inconel 625 alloy was initially aluminide coated by halide-activated pack cementation at 700 °C for 4 h using fine (40–45 µm) globular and coarse (10–75 µm) ligament aluminum particles. Microstructural features and hardness variation of the coatings along with their oxidation behavior at 1000 °C during 50 h were investigated to reveal the effect of pack characteristics on the properties. Investigations revealed that (i) a homogeneous and continuous coating layer was formed on the surface without internal oxidation, (ii) a thicker coating (∼60 µm) was formed due to the pack consisting of coarse particles, (iii) a higher hardness value (1369 HV0.5) was measured for the coated alloy using fine particles in the pack, and (iv) the coating with coarse powder exhibited higher oxidation resistance during the first 50 h of oxidation test period. Secondly, superalloy was coated at different temperatures (700 and 1000 °C) and times (2 and 4 h) using coarse particles. In this stage, the findings showed that by increasing process temperature and time, the accumulation of aluminum on the superalloy surface increased and the oxidation tendency remained at a lower level in coatings containing thicker layers.
