Description
Summary:The Ice Engineering Information Exchange Bulletin is published in accordance with AR 25-30 as one of the information exchange functions of the Corps of Engineers. It is primarily intended to be a forum thereby information on ice engineering work done or managed by Corps held offices can be disseminated to other Corps offices, of the U.S. Government agencies, and the engineering community in general. The topic of this issue concerns evaluation of coatings for icing control at hydraulic structure. Adhesion of ice to surfaces creates problems for many industries, including hydropower and navigation. At present, ice removal techniques are costly, hazardous, and time-consuming. Andersson and Andersson (1992) reported that one hydropower station in Sweden had ice-related costs averaging $0.2 million per year over a 10-year period. Annual maintenance costs incurred at Corps of Engineer projects as a result of ice problems were estimated to be $33 million in 1992 (Haynes et al. 1993). Numerous commercially available materials, coatings, and paints are advertised to have low friction or non-stick properties. Some of these coatings are also marketed as icephobic (i.e., significantly lowering the adhesion strength of ice). We have measured the ice adhesion strength for many of these coatings and materials in the laboratory to rank their relative performance (e.g., Hachnel and Mulherin 1998). Our most recent study focused on the suitability of these materials and coatings for controlling icing at hydraulic structures. The original document contains color images.
