Ferrite magnets, we also call them ordinary magnets, ceramics, black magnets, etc., are a kind of magnetic material that is widely used. The common shapes are ring, round, rectangular, arc and irregular shapes. Its surface How to deal with it in general? What can be done? Let’s talk to everyone today.
How to deal with the surface of ferrite magnet?
Ferrite magnets have good corrosion resistance and will not corrode when placed in water. They can resist the chemical erosion of many alkaline solutions, dilute acids, organic solvents and some hydroxides. They are very suitable for salt water environments (no corrosion problems at all). It can be etched with acid (such as hydrochloric acid), and the surface is generally not treated, that is, no protective coating is required.
Ferrite permanent magnets can be painted and nickel-plated, mainly in medical applications.
For most applications, ferrite magnets (ceramic magnets) do not require any coating and can be used as is.
