Corrosion protection of sintered NdFeB magnets by phosphating

A diffusion controlled process, such as diffusion through the corrosion products precipitated inside the pores, can be envisaged as responsible for this response. The polarization direction was reversed at 1.3 V, and the current measured decreased considerably during the reverse scan. During the reverse

Degradation and crystalline reorganization of hureaulite ...

In the phosphating process of steel, manganese and iron can independently form the structure of hureaulite in their respective phosphating systems,, . Since the manganese and iron are interchangeable in the crystal lattice of the hureaulite, the structure can be represented as: (Mn, Fe) 3 (PO 4 ) 2 − 2(Mn, Fe)HPO 4 − 4H 2 O [8], [9] .

Wastewater treatment of iron and zinc phosphate …

2007. A. Iron phosphating is a Federal categorical process, with defined pretreatment discharge limits. The most likely contaminant in spent rinse water is zinc, if you are applying this coating on galvanized steel. An adjustment of the pH to 9 - 9.5, followed by the addition of flocculant, and settling, should leave the residual Zn in the decant below this limit.

manganese washing process

Phosphating is the process of converting a steel surface to iron phosphate. This is mostly used as a pretreatment method in conjunction with another method of corrosion protection. A layer of phosphate coating typically includes iron, zinc or manganese crystals. Read more .

Process Control For Phosphate Coating

phosphating with a calcium-modified solution exhibited a flat platelet struc- ture (Fig. ll). Other parts that were subjected to an alkaline cleaner that had a titanium salt in it also exhibited a flat platelet structure. In this case, the applicator had no idea what was responsible for the fine grain structure.
