Juni 1, 1 Berlin Government sponsorship: DM 4,7.0 Sponsorship ratio: 1 Yo 1. Purpose of the project The goal of this project was to examine the possibilities for substituting conventional alumin- ium coatings. The studies targeted several sub-goals: The chemical, physical and technolo ical properties of superpure aluminium coatings deposit- ed from aprotic trialkylaluminium %ctrolytes had to be determined first through the use of objective and reproducible test methods. For this urpose, various measurement,techniques were investigated with respect to their suitability krthe measurement task. In this context, it had to be considered that the coatin properties could be greatly influenced by,chemical or electrolytic post-treatment. Additionaysub-goals were to compile propert profile for super- property rofile of chemical or electrolytic post-treatment as regards its effect on the surface -quality orsuperpure aluminium. This applies in particular to workpieces with complicated external form. Still another goal of the studies was to compile roperty profilesfor metal coatingswhose sub- stitution appears to be particularly desirable {om an economic, environmental or technolo-, gical standpoint. These include coatings, made of metals such as cadmium, nickel, silver and gold. Insofar asthe individual characteristics of these metal coatings could not be reliablydeter- min
