In Cu/ZnO/s.a. (synthetic air) and in Cu 2 O/ZnO/s.a. some CuO can be observed indicating oxidation, but especially Cu 2 O diffraction peaks can be clearly identified. These Cu 2 O peaks are unusually large relative to the ZnO peaks as compared to unmilled Cu 2 O/ZnO. The presence of Cu 2 O is remarkable, as almost complete …

The investigation was performed using pure zinc (denoted as Zn) and alloys with 0.6 and 1.3 wt percent of magnesium addition (called Zn-0.6 Mg and Zn-1.3 Mg). Pure zinc …
A. Mechanical plating deposits a layer of zinc over the surface of the items to be plated by friction. the result is a zinc-coloured matte finish, and corrosion resistance similar to galvanising. I've seen it done in a cement mixer, I've also seen zinc-loaded wire-wheels for for use in angle grinders ⇦ this on eBay or Amazon [affil links].
After grinding, the (002) relative texture coefficient of commercial zinc metal increases from 10.58 to 42.28, indicating a significant more (002) planes exposure. As …

Mechanical vs. Electroplated Zinc. Is there any evidence or reason to believe that mechanically-plated zinc with give better corrosion protection than electroplated zinc on steel in a typical construction environment? Larry Hanke Minneapolis, Minnesota 1998. In my opinion zinc is zinc, unless a process contaminates the surface in some way.
