MIL-DTL-16232 TYPE M
Manganese Phosphate Coating
Phosphate Conversion Coatings
Manganese Phosphating Conversion Coatings MIL-DTL-16232 Type M is an excellent coating for wear reduction and corrosion resistance when used with supplementary treatments such as oil, wax, lubricant, painting or powder coating. Manganese phosphate (mphos) MIL-DTL-16232 Type M coatings are typically much heavier than Zinc phosphate MIL-DTL-16232 Type Z coatings. Manganese phosphate coatings normally exhibit a uniform dark grey color that is durable and none light reflective.
MIL-DTL-16232 Type M phosphating is commonly used for the following types of components:
