This article is aimed to study the effect of laser treatment AISI 304 stainless steel on corrosion resistance and chemical composition surface layer. The samples were irradiated using two quite different sources: IPG Yb:glass fibre (? = 230 ns, ? 1062 nm) Trumpf TruMicro Series 2020 fiber 260 fs–20 ps, 1030 that is, in both long ultra-short pulse duration regime. It allowed observation complete...

in this paper, the nucleation and growth of diamond/diamond-like coatings on austenitic (aisi 316) and ferritic (aisi 430) stainless steel substrates have been investigated using torch technique. the effects of substrate surface preparation has also been studied. the quality of coatings produced has been examined using optical and scanning electron microscopy, x-ray diffraction, raman spectrosc...

Heterotrophic bacteria (11 genera, 14 species, 25 putative strains) were isolated from drinking water, identified either biochemically or by partial 16s rDNA gene sequencing and their adherence characteristics were determined by two methods: i. thermodynamic prediction of adhesion potential by measuring hydrophobicity (contact angle measurements) and ii. by measuring adherence to eight differen...
