Friction coefficient μ of phosphating coating
Introduction
The friction coefficient is a measure of how easily two surfaces interact with each other when moving relative to one another. Many factors contribute to the calculated value for a friction coefficient. The hardness, surface roughness, and type of material used are all important to c......

The basic principle of phosphating - phosphating process
Phosphating is a process that is used by many industries due to its numerous benefits. It involves the application of an acidic solution containing phosphoric acid and other chemicals to the surface of a metal object. This acid solution chemically reacts with the surface of the object, leading to ......
The basic principle of phosphating - pretreatment before phosphating
Phosphating is a common coating technique for metals, and it involves the controlled application of an inorganic phosphate to the metal surface. Phosphates form a protective coating that resists corrosion and provides better adhesion for paint, lubricants, and other coatings.
Phosphating is a com......
Waste liquid treatment method of zinc phosphate phosphating treatment liquid
Treatment of Wastewater from Zinc Phosphate Chemical Conversion Coating
Abstract
This article will discuss the potential treatment options for wastewater effluents generated from the zinc phosphate chemical conversion coating process. The article begins by describing the zinc phosphate process a......
Discussion on Pseudo-Zinc-Calcium Phosphating Solution
Introduction
Zinc-calcium phosphate systems are a composite coating material consisting of zinc and calcium phosphate particles combined with an organic binder. The combination of the two materials gives unique physical and chemical properties to the coating. The combination of zinc and the organ......

Acid Washing
Acid washing is a process in which metal surfaces are cleaned or have their properties altered through the use of acids. This process is often used for the removal of unwanted contaminants, such as rust and scale, that accumulate on various surfaces during manufacturing or exploitati......
The principle of pickling billets
The Principle of Pickling Steel Billet
Pickling is a process used to remove impurities and rust from steel surfaces. It is one of the most common surface treatments used in the production of steel products. Pickling is often followed by decarbonizing and phosphating, which further refines the sur......
Control of Ferrous Sulfate Content in Pickling
Control of Ferrous Sulfate Content in Acid Washing
Acid washing is the process of removing mineral deposits, scale, and other surface deposits from masonry and metal surfaces by the use of chemicals, water, and heat. Acid washing is most often performed with sulfuric or hydrochloric acid, while ......
Acid Sulfate Cadmium Plating Bath Recipe
Introduction
Zinc plating is a process of applying a thin layer of zinc to a steel or iron surface. The zinc layer is quite thin, typically less than 0.25mm, and is primarily used to provide protection against corrosion. It is applied in a variety of processes, including electroplating and hot-di......
