Dry coatings and ecodesign

Corrosion properties of in situ laser remelted NiCrBSi coatings comparison with hard chromium coatings

“…To carry out this Life Cycle Assessment, some data must be checked (Table 3). Other data can be found in the current literature (Serres et al, 2009a). On the contrary, the technical data of the coatings remelted by flame (Bergant and Grum, 2009), thermal treatment (Miguel et al, 2003) or laser (González et al, 2007b) were found in the literature.…”

“…Indeed, environmental regulations applied to the surface coating field are nowadays intensive, especially in Europe. In recent works, the environmental assessment of dry coatings carried out by thermal spraying was investigated (Serres et al, 2009a). This work suggests that the ecodesign of dry coatings is possible and it clearly indicates that APS and laser cladding are green technologies in comparison with hard chromium plating.…”

“…SimaPro is a LCA software that allows materials and processes to be evaluated for the types and amounts of emissions that are considered damaging to environment. The Eco-Indicator 99 methodology was already used in previous works where attention was centered in the analysis of dry coatings carried out by thermal spraying and laser cladding (Serres et al, 2009a). The Eco-Indicator 99 is both a science based impact assessment system for LCA and a realistic ecodesign method.…”

“…This result is related to the laser, often compared to a green technology (Serres et al, 2009a). The efficiency of laser operations is high, which includes lower gas, electricity and feedstock material consumptions, and also reduces all emissions.…”

High temperature tribological properties of NiCrBSiCFe plasma-sprayed coating on austenitic stainless steel substrate

“…Tribological characterization was carried out in order to determine the alternative potential of NiCrBSi coatings compared to electrolytic hard chromium plating, in applications to resist wear [13]. Three groups of MoNiCrBSi coated specimens were produced with different spray distance parameter.…”
