A variety of solutions can be used for conversion coatings, depending on the type of conversion coating required and processing conditions.
For metal surface treatment, such as galvanizing, chromium plating, etc., the corresponding electroplating solution or chemical plating solution is usually used. These solutions contain the required metal ions and additives to achieve the desired surface treatment.
For chemical conversion films, such as oxide films, passivation films, etc., acidic or alkaline solutions are usually used. These solutions contain the required chemicals to achieve the desired surface transformation.
In addition, for some special conversion coating treatments, such as nanofilm preparation, etc., special solutions or mixtures may be required.
It should be noted that different solutions may have different chemical properties and application ranges, so corresponding safety operating procedures and precautions need to be followed during use. At the same time, it is also necessary to select the appropriate solution and treatment process according to specific needs and processing conditions to achieve the best surface treatment effect.
