Standards for titanium anodizing are given by AMS 2487 and AMS 2488. AMS 2488 Type III anodizing of titanium generates an array of different colors without dyes, for which it is sometimes used in art, costume jewellery, body piercing jewellery and wedding rings. The color formed is dependent on the thickness of the oxide (which is determined by ...
In conventional anodizing, this layer of oxide is grown on the surface of the metal by the application of electrical potential, while the part is immersed in an acidic electrolyte. In plasma electrolytic oxidation, higher potentials are applied. For example, in the plasma electrolytic oxidation of aluminum, at least 200 V must be applied.
anodizing – electrolytic passivation process used to increase the thickness of the natural oxide layer, producing a porous surface which can accept organic or inorganic dyes easily. In the case of titanium, niobium, and stainless steel, the colour formed is dependent on the thickness of the oxide (which is determined by the anodizing voltage).
Recent revisions of ASTM B633 defer to ASTM F1941 for zinc plating mechanical fasteners, like bolts, nuts, etc. 2019 is the current revision for ASTM B633 (superseded the revision from 2015), which raised required tensile thresholds when confronting hydrogen embrittlement issues and addressed embrittlement concerns in a new appendix.
A conversion coating is a chemical or electro-chemical treatment applied to manufactured parts that superficially converts the material into a thin adhering coating of an insoluble compound.
(Reuters) -U.S. President Joe Biden's administration has notified Congress of a proposed $8 billion arms sale to Israel, two U.S. officials said, with Washington maintaining support for its ally ...
The oldest and most widely used specification for hot black oxide is MIL-DTL-13924, which covers four classes of processes for different substrates. Alternate specifications include AMS 2485, ASTM D769, and ISO 11408. [citation needed]
When plating, consider serving with a small dish of hot honey for any guests who are craving a little heat with their sweet, salty, and smokey appetizer—or go ahead and drizzle some right on top ...
