The purpose of the MéLiMo Project is to develop coatings to protect metal surfaces from liquid metals thereby eliminating their wetting. More specifically, MéLiMo will focus on making surfaces resistant to liquid aluminum. MéLiMo is a TRL 1-3 (Technology Readiness Level) presented within the scope of a collaborative research grant application by the Université de Sherbrooke and the NSERC (Natural Sciences and Engineering Research Council) with support from the CQRDA (Centre québécois de recherche et de développement de l'aluminium), METAL7 and Aluminerie Alouette. The expertise of the Université de Sherbrooke research scientists in the field of material synthesis is crucial, particularly in the combinatorial synthesis of new coating compositions and anti-wetting textures. The Université de Sherbrooke's Plasma Engineering Laboratory can generate nearly 225 new compositions per day using induction plasma technology combined with suspension synthesis technology (invented by Professor Gitzhofer); composition and multi-step analysis techniques are adapted to the large number of samples produced. This synthesis techniques use precursors (powders, liquids or gases or mixtures such as suspensions) which can react and allow new compositions to be deposited. For the synthesis of new compositions, suspensions will be used, with ethanol and glycerol as carrier liquids for oxides, and nitrogen or boron-based liquids for nitrides and borides. A patent application was recently filed for using these special liquids to make borides and nitrides from suspensions. As for composite coatings, they can be designed by changing the size and composition of the suspension precursors during the suspension projections and also by adding to the existing process a DC plasma spraying gun.

MéLiMo项目的目的是开发涂层，以保护金属表面免受液体金属的影响，从而消除其润湿。更具体地说，MéLiMo将专注于制造耐液态铝的表面。MéLiMo是TRL 1-3（技术准备水平），由舍布鲁克大学和NSERC（自然科学和工程研究理事会）在CQRDA（魁北克铝研究和发展中心）、METAL 7和Aluminerie Alouette的支持下，在合作研究资助申请范围内提出。舍布鲁克大学研究科学家在材料合成领域的专业知识至关重要，特别是在新涂料组合物和抗湿纹理的组合合成方面。舍布鲁克大学的等离子体工程实验室使用感应等离子体技术结合悬浮合成技术（由Gitzhofer教授发明），每天可以产生近225种新的组合物;组合物和多步分析技术适用于生产的大量样品。这种合成技术使用前体（粉末、液体或气体或混合物，如悬浮液），其可以反应并允许沉积新的组合物。为了合成新的组合物，将使用悬浮液，其中乙醇和甘油作为氧化物的载液，氮或硼基液体用于氮化物和硼化物。最近提出了一项专利申请，利用这些特殊的液体从悬浮液中制备硼化物和氮化物。至于复合涂层，它们可以通过在悬浮液喷射期间改变悬浮液前体的尺寸和组成来设计，并且还可以通过向现有工艺添加DC等离子体喷枪来设计。
