The phrase "acid pickling" is correct and usable in written English.
It is typically used in the context of metal treatment processes where acids are used to remove impurities or oxides from the surface of metals.
Example: "The manufacturer employs acid pickling to ensure the metal surfaces are clean and ready for further processing."
Alternatives: "acid etching" or "chemical pickling".
A chromium-free conversion coating for AZ91D magnesium alloy has been obtained by using a phosphate permanganate solution, which has been developed out without acid pickling.
Magnesium alloy was disposed by three kinds of acid pickling formula and activation formula and the effect of the three kinds of acid activation formula on magnesium alloy was studied by contrast experiment.
In one procedure, an extra step, consisting of immersion in nitric hydrofluoric acid solution for 30 s (desmutting bath), was carried out after immersion in sulfuric –phosphoric acid solution (acid pickling bath).
The experimental results indicated that after disposed by acid pickling formula of HNO3 25 ml/L, H3PO4 25 ml/L, room temperature and activation formula of NH4H2PO4 80–100 g/L, NH4F 30 50 g/L, room temperature, magnesium alloy could realize electroless nickel plating directly.
An Ni layer of approximately 20 μm in thickness was electro-deposited on the hardmetal YG6 surface, and the electroplating process was performed in the following sequence: mechanical grinding (on the diamond discs of 240# → 400# → 600# → 800#, respectively) → chemical deoiling and degreasing → electro cleaning → acid pickling → alkali cleaning → nickel plating.
In several industrial processes such as acid cleaning, acid well acidizing, and acid pickling, rust and contaminated scales were generally removed using acid solutions.
A Ni B coating was electroless-deposited directly on acetic acid pickled AZ91D.
In Japan gastric ulcer is more common than duodenal ulcer and is thought to be related to the raw fish and acetic acid pickles of the traditional diet.
(b) The term operation shall mean any step in the electroplating process in which a metal is electrodeposited on a basis material and which is followed by a rinse; this includes the related operations of alkaline cleaning, acid pickle, stripping, and coloring when each operation is followed by a rinse.
Hydrochloric acid is the most commonly used pickling acid in industries [1].
After death, its body may have been colonised by bacteria that produce lactic acid, which "pickled" it, preserving the mammoth in a nearly pristine state.
