Is Graphite corrosive to anodized aluminum?

2013/12/22001 A. Hello John! I'm assuming that you're concerned with galvanic corrosion -- the graphite making the aluminum corrode faster by being cathodic to it. If so, don't worry- the hard anodize serves as a sufficient barrier to be a proper fix. Check out Mil-STD-889 [affil. link to spec at Techstreet] on Dissimilar Metals, which lists hard anodizing as the premier mitigation step when you have

(PDF) Strengthening behavior of few

Several processes have been introduced to exfoliate graphite to single-layer or few-layer graphene by mechanical and/or chemical means [3][4][5]. Mechanical exfoliation using a tape dispenser [2] or atomic force microscopy (AFM) [6] has exhibited inadequate productivity for large-scale industrial applications.

Transparent, flexible solar cells

The PCEs for all their graphene/graphene devices — on rigid glass substrates as well as flexible substrates — ranged from 2.8 percent to 4.1 percent. While those values are well below the PCEs of existing commercial solar panels, they're a significant improvement over PCEs achieved in prior work involving semitransparent devices with all-graphene electrodes, the researchers say.

Aluminum

The interaction of liquid and solid aluminum with the graphene and graphite surfaces is studied using the density functional theory and a molecular dynamics simulation. The Morse potential is parameterized using the results of ab initio calculations in order to describe the interaction between aluminum and carbon atoms. This potential is used to investigate the interaction of a molten aluminum

The enhancement of corrosion protection of metals and alloys by coating with simple, low cost, and highly adhered layer is still a main goal of many workers. In this research graphite flakes converted into graphene oxide using modified Hammers method and then reduced graphene oxide was electrodeposited on stainless steel 316, copper, and aluminum for corrosion protection application in
