Ti(1-x)AlxN hard coatings were prepared by reactive magnetron sputtering onto steel substrates (51CrV4 – 1.8159) and subsequently exposed for a short-time (~1 s) to high-flux electron beam (EB) treatment. Morphology, composition and the structure o

Subsequent electron beam hardening (EBH) of hard coated steels results in a significant improvement of the load-bearing capacity of the base material. The success of this combined treatment is based on the coatings' resistance to crack formation. Thi

This paper deals with the results of combining Ti 1 − x Al x N coatings with a subsequent electron beam surface-hardening process. The coatings – differing in their chemical composition (Al = 17…30 at.%; Ti = 18…30 at.%) and thickness (1–6

Mechanical surface treatments like machine hammer peening and deep rolling can substitute an essential part of the manual polishing time in the conventional process chain of die and mold production. However, the increasing use of high strength steels

Due to the outstanding properties of cubic boron nitride (c-BN) – c-BN is the second hardest of all known materials, has a high wear resistance and a high thermal stability – this material is very promising for a broad range of applications, espe

Background. It has been hypothesized that in renal failure, exogenous glycation compounds from food accumulate and play a major pathogenetic role when renal excretion is impaired. Methods. To address this, a diet containing a defined amount of the ly

In this investigation, an electron beam hardening (EBH) procedure was applied to heat-treatable steel 51CrV4 coated with Ti(1-x)AlxN hard coatings, where x ranged from 0.3 to 0.6. The coatings with variable composition and mechanical properties were

Carbon based multilayer coatings were prepared by plasma assisted chemical vapor deposition (PACVD) using methane (CH 4 ) and hexamethyldisiloxane (HMDSO) or methane and tetramethylsilane (TMS) as precursors. These coatings were deposited in a modifi
