2015-01-2149
This paper depicts icephobic coating performances of 274 different coatings, including 11 grease-type coatings, which were tested over the past 10 years in various research projects at the Anti-Icing Materials International Laboratory (AMIL). ...The first method, the ice Centrifuge Adhesion Test (CAT), measures the force required to separate the accreted ice from the coating (e.g. adhesive failure). The test involves simultaneously icing, under supercooled precipitation, the extremity of bare reference and freshly coated aluminum samples. ...Overall, the performance of tested coatings over the years remains similar with a wide range of ARF values, 0.5 to 1000, corresponding to stresses between 0.8 MPa and 0.0005 MPa, respectively.

Hot-dip galvanneal sheet is produced throughout the world and several companies have developed specific testing methods to evaluate the adhesion properties of the coating to the steel sheet. There is no universal standards for individual companies to compare the quality of their coating to other commercial products. ...There is no universal standards for individual companies to compare the quality of their coating to other commercial products. This paper reports on a light absorption technique to assess the galvanneal coating powdering characteristics after bend testing. ...This paper reports on a light absorption technique to assess the galvanneal coating powdering characteristics after bend testing. Specimens are taped and subjected to a bend test, and then the tape is stripped, placed on a glass slide and evaluated in a spectrophotometer.

2006-01-3155
However despite the suspected test dependencies, no detailed open research literature on the fastener shear test, especially shear strength variation via single and double shear approaches, and factors including surface coatings that affect tested shear values, has been conducted. Thus, the objective of this program is to systematically evaluate the effect of coating tribology on the threaded fasteners shear property tested via single shear and double shear testing methods. ...Thus, the objective of this program is to systematically evaluate the effect of coating tribology on the threaded fasteners shear property tested via single shear and double shear testing methods. ...To determine if correlation exist between surface properties and shear strength, detailed physical property measurements on each individual fastener including surface friction coefficients, surface roughness, coating thickness, and diameter were conducted. Detailed statistical analysis was conducted to identify relationship between surface coating tribology and shear strength.
