New metal plastic laminates from polyolefin compositions having high impact resistance and high temperature flow resistance

Abstract: Polyolefin compositions having a high level of impact resistance and high temperature flow resistance comprising 30 to 90 weight percent resin containing greater than 50 to less than 75 weight percent of polyolefin and greater than 25 to less than 50 weight percent elastomer, and 10 to 70 weight percent filler are described. Metal plastic laminates are prepared by sandwiching a plastic sheet prepared from the polyolefin compositions between two sheets of metal. Figure 2 shows the impact strength of polyolefin resin-filler compositions in which the resin-filler weight ratio is constant but the elastomer content of the resin varies.

A Study of the Entry and Removal of Hydrogen during Coating and Thermal Treatment of Steel

Abstract: High strength steel wires were charged with hydrogen, electroplated with nickel, and baked at 191 C for 3 hours to relieve hydrogen embrittlement. To follow the entry and removal of hydrogen and its effects, measurement of (1) hydrogen contents of the wire and the coating, and (2) cracking susceptibility of the wire were made during each step of these processes. The results show that hydrogen introduced into steel during processes such as preplate acid cleaning and electroplating is initially present in a mobile form that causes embrittlement. Although postplate baking can relieve embrittlement by simply driving mobile hydrogen out of the steel, this work clearly demonstrates that baking can also relieve embrittlement by an alternate mechanism believed to involve driving the mobile species into internal trap sites. Because steel can accommodate process hydrogen in this innocuous trapped state, the total hydrogen content of steel as determined by high temperature extraction does not provide a reli...
