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...

The electrochemical behavior of the corrosion resistance AISI 304 embedded in concrete manufactured as indicated by ACI 211.1 method was evaluated. specimens were exposed for more than 150 days to highly aggressive marine-sulfated environment, solution with a concentration 5% NaCl and Na2SO4. technique Resistance Linear Polarization (Rp) used determine rate (Icorr) monitoring potential (Ecorr)....

Abstract The availability of commercial ultrafast lasers reaching into the kW power level offers promising potential for high-volume manufacturing applications. Exploiting available average is challenging due to process limits imposed by particle shielding, ambient atmosphere breakdown, and heat accumulation effects. We experimentally confirm validity a simple thermal model, which can be used e...
