A strategy for the selection of multiple materials and processes fulfilling inherently incompatible functions: The case of successive surface treatments

Multiple surface treatment technologies are used as an example of: (i) simultaneous selection of materials and processes; (ii) selection of multiple materials each of which fulfills different functions; and (iii) selection of materials with incompatibility issues. A questionnaire-based screening algorithm uses a small surface treatment database mostly filled in with Booleans to address these issues. It relies on the fact that functions can be brought by the first treatment, the latest treatment, all treatments or at least one treatment, like for corrosion resistance. Functions are associated with attributes and combinations of treatments are suggested. The system is illustrated for four examples (automobile corrosion protection, electronic packaging, aluminum die casting and wear protection of gears) and successfully proposes candidates from literature as well as alternatives. It can be used as an exchange tool between the users and the providers of surface treatments, as a marketing tool for a specific family of processes or as a complement to industrial drawing software.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

End-of-life management of computers in Brussels: environmental comparison of two treatment chains

Driven by environmental concerns and new legal requirements, the targeted collection rates of waste electrical and electronic equipment (WEEE) are increasing and waste operators seek to expand their collection. In this research, we compare the environmental impacts of two existing end-of-life treatment chains of computers in Brussels based on a life cycle assessment. The first chain is managed by the association responsible for complying to the take-back obligation on behalf of manufacturers in Belgium. The second one is run by work integration social enterprises (WISE) which prioritize reuse and a deeper manual dismantling of WEEE prior to mechanical treatment. The results show that the latter chain provides an environmental advantage up to 69% in comparison to the former thanks to reuse and a higher material recovery rate. Thus, if the first chain increases its collection in detriment of WISE, the global environmental benefits of the treatment of WEEE will decrease.SCOPUS: cp.pinfo:eu-repo/semantics/publishe

Sliding Wear Behavior of Friction Couples Primarily Selected for Corrosion Resistance: Iron Boride/Iron Boride and Iron Boride/Yttria-Stabilized Zirconia

Wear mitigation in a sliding couple is challenging if wear has to be minimized on both surfaces. In this paper, ball-on-disk testing is performed on sliding couples where both surfaces (ball and disk) are treated for wear resistance. Studied materials are pack borided H13 tool steel (ASTM A681), pack borided AISI 420 stainless steel (ASTM A276) and plasma sprayed yttria-stabilized zirconia (YSZ). Borided H13 steel exhibits a single phase Fe2B layer, while AISI 420 has a double phase layer, with FeB on the outer surface. Both FeB/Fe2B and FeB/YSZ couples generate three-body abrasion. In the latter case, mass transfer occurs from the ball to the disk as well. Friction coefficient is ~0.6 for the AISI 420/Fe2B and FeB/Fe2B sliding pairs, with less vibration on the latter and wear rates close to 10−3 mm³·(N·m)−1 for both the ball and the disk. In comparison, the FeB/YSZ pair has a friction coefficient of ~0.65, a similar total mass loss, but a much higher wear rate for YSZ than for FeB
