The following tips and tricks work on aluminum and magnesium-alloy wheels. Scuffed, Machined Lip Wheel Repair To repair a machined outer lip typically found on Rays/Volk and Forgeline wheels you need a flat file and a round rat tail or needle file, a popsicle stick, 400-800 grit sand paper, masking tape and a small bottle of touch-up clear coat.
hardening ability of the alloy and Zr is added as a grain refiner. In this paper, rare earth element neodymium Nd is added to Mg-0.3Zn-0.32Zr alloy. The effects of Nd on the microstructures and mechan ical properties at elevated temperature of the magnesium alloy
Wider implementation of ultralight magnesium (Mg) alloys in engineering appliions can be achieved if the mechanical properties of mass produced as-cast alloys can be further enhanced. Grain refinement of aluminum alloys has supported such initiatives over the past few decades; however, a potent and cost-effective grain refiner for common aluminum containing Mg alloys remains elusive

magnesium alloys is a serious problem in the cooling system of an engine block [ ], which restricts their appliions. During the past decade, there were many research works which focused on the corrosion behaviour and mechanism ofmagnesiumalloys[ ].
were then mounted on a flat block (or the Gatan model 623 disc grinder) with double sided tape. Mounting can also be done using an acetone soluble cement. The speci-mens were then hand polished through a sequence of 200, 300, 400, and 600 grit plates.
Vol. 6, No. 1, 2003 Electron Microscopic Studies of Anodic Oxide Films on the AZ91HP Alloy 105 A porosity up to 52% was calculated in this way. Al-though this calculated value seems to agree well with the visual impression one gets from the micrographs, it has

Spark Plasma Sintering (SPS) process has been used to develop a novel grain refiner Al-SiC master alloy for AZ91E Mg alloys. When the Al-SiC master alloy was added to molten AZ91E alloy, the Al matrix melted and allowed the SiC particles to distribute homogeneously throughout the molten AZ91E alloy. After addition of 0.1 wt.% Al-SiC master alloy to AZ91E alloy, the mean grain size decreased
The objectives of this study were to reduce the corrosion rate and increase the cytocompatibility of AZ31 Mg alloy. Two coatings were considered. One coating contained MgO (MAO/AZ31). The other coating contained Cu2+ (Cu/MAO/AZ31), and it was produced on the AZ31 Mg alloy via microarc oxidation (MAO). Coating characterization was conducted using a set of methods, including scanning electron
