The system includes a cleaning composition having a pH greater than 8.5 or a solvent, and a pretreatment composition comprising an organophosphate compound and/or an organophosphonate compound. The method includes contacting a substrate surface with the cleaning composition or the solvent, and contacting the surface with the pretreatment composition. Also disclosed are substrates treated with one of the systems or methods. Also disclosed are magnesium or magnesium alloy substrates wherein, between the air/substrate interface and 500 nm below the air/substrate interface (a) oxygen and magnesium are present in a combined amount of at least 70 atomic %; (b) carbon is present in an amount of no more than 30 atomic %; and/or (c) fluoride is present in an amount of no more than 8 atomic %, wherein atomic % is measured by XPS depth profiling.

Abstract: In one aspect, a shroud assembly for headgear includes a frame having a shape that matches a contour of the headgear. An insert is formed of metal or metal alloy and is attached to a front side of the frame. The insert is configured for removable attachment to a mounting assembly. The frame includes first and second spaced flexible walls disposed on the front side of the frame on opposite sides of the insert. The first and second flexible walls are spaced a sufficient distance apart to provide an interference fit between the mounting assembly and the first and second flexible walls. In another embodiment, the shroud assembly further includes a friction pad disposed on a rear surface of the frame for increasing friction between the shroud assembly and the headgear. In another aspect, a method for attaching a mounting assembly to headgear is provided.
