Wear behavior of adaptive nano-multilayered AlTiN/MexN PVD coatings during machining of aerospace alloys
A. Biksa,Kaoru Yamamoto,G.K. Dosbaeva,Stephen C. Veldhuis,German S. Fox-Rabinovich,A. Elfizy,T. Wagg,L.S. Shuster +7 more
TL;DR: In this article, the nano-multilayered AlTiN/Me x N PVD coatings are applied to carbide tooling for cutting hard to machine alloys such as Ni-based Inconel 718 superalloy and Ti-based TiAl6V4 alloy.
Journal ArticleDOI
Structure, properties and wear performance of nano-multilayered TiAlCrSiYN/TiAlCrN coatings during machining of Ni-based aerospace superalloys
German S. Fox-Rabinovich,Ben D. Beake,Kaoru Yamamoto,Myriam H. Aguirre,Stephen C. Veldhuis,G.K. Dosbaeva,A. Elfizy,A. Biksa,L.S. Shuster +8 more
TL;DR: In this article, nano-multilayered TiAlCrSiYN/TiAlCrN coatings have been developed with various ratios of Ti/Al/Cr within Si+Y containing nano-layers for machining direct aged Inconel (DA) 718 and powder metallurgical ME 16 Ni-based superalloys.
Journal ArticleDOI
Wear behaviour of coated carbide tools during machining of Ti6Al4V aerospace alloy associated with strong built up edge formation
M.S.I. Chowdhury,Shahereen Chowdhury,Kaoru Yamamoto,Ben D. Beake,Bipasha Bose,A. Elfizy,D. Cavelli,G.K. Dosbaeva,Maryam Aramesh,German S. Fox-Rabinovich,Stephen C. Veldhuis +10 more
TL;DR: In this paper, a self-lubricating TiB 2 PVD coating was used for rough turning operation with strong built-up edge formation, which can be achieved through the application of self lube.
Journal ArticleDOI
Investigations of White Layer Formation During Machining of Powder Metallurgical Ni-Based ME 16 Superalloy
TL;DR: In this paper, the surface integrity of machined parts made from the advanced Ni-based superalloys is investigated using optical metallography and a high-resolution scanning electron microscope with energy dispersive x-ray spectrometer (HR SEM/EDS).
Journal ArticleDOI
Oxide scales formation in nano-crystalline TiAlCrSiYN PVD coatings at elevated temperature
G.K. Dosbaeva,Stephen C. Veldhuis,Kaoru Yamamoto,David Wilkinson,Ben D. Beake,N. Jenkins,A. Elfizy,German S. Fox-Rabinovich +7 more
TL;DR: In this article, nano-crystalline TiAlCrSiYN plasma vapor deposited (PVD) coatings were developed for oxidation and wear protection at elevated temperatures, and compositional tuning of the coatings was performed to enhance oxidation protection.
