Microorganisms as a Replacement for Metal Working Fluids

摘要: Most of the several billion liters metalworking fluid (MWF) used worldwide and annually are water-based thus prone to a microbial contamination. The growth leads deterioration therefore loss quality technical performance. In most cases, biocides, which pose potential risk health environment, reduce load. To avoid these limitations, paradigm shift using microorganisms in positive way manufacturing process as lubricant is investigated this paper. Some able synthesize equivalent MWF components like e.g. fatty acids or sulfur compounds. Due fact, it possible create regenerative system on microbiological basis for substitution mineral oil containing components. demonstrate lubrication bacteria, preliminary investigations were conducted Brugger-tribotester. Against background, approach presented here intends investigate properties special influence cell counts behavior respectively. results tribological tests show that microbial-suspensions exhibit Brugger-values high highly concentrated conventional indicate replace respective
