Is black phosphate corrosion resistant
WebCaustic corrosion (and caustic embrittlement, discussed later) does not occur, because high caustic concentrations do not develop (see Figure 11-3). Figure 11-4 shows the phosphate/pH relationship recommended to control boiler corrosion. Different forms of phosphate consume or add caustic as the phosphate shifts to the proper form.

WebThe phosphate coating, which is black in appearance, is preferred, as it is the more rust-resistant. However, this does not sanction use in wet or exterior situations. Zinc-coated screws, when they begin to rust, will … Phosphate coatings are also commonly used as an effective surface preparation for further coating and/or painting, providing excellent adhesion and electric isolation. Phosphate coatings are often used to protect steel parts against rusting and other types of corrosion. However, they are somewhat porous, so this use requires impregnating the coating with oil, paint, or some other sealing substance. The result is a tightly adhering dielectric (electric…
