In addition, iron can be dragged into the bath from acid pickles high in iron concentration and this iron will readily react to form red oxide. If iron is being dragged into the bath, then the problem can be eliminated by a more thorough cleaning and a more thorough rinsing prior to immersing the parts in the black oxide bath.

wheel is essential for quality grinding since each process has its ideal specifications for use [12, 13]. In this sense, grinding wheels are generally classified as conventional or super abrasive [14]. Among conventional ones, aluminum oxide and silicon carbide wheels belong, while super abrasives include mainly cubic boron nitride (CBN) [15].
