Discussion on Several Problems of Electroplating Pre-treatment of Magnetic Materials
Introduction
In the process of electroplating, surface pre-treatment is an important step for the completion of the entire surface treatment process. The pre-treatment of magnetic material electroplating includes degreasing, conversion film, activation and other processes. Due to the various cond......

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......
Study on Electroless Nickel Plating Process for Plastics
Research on Plastic Chemical Nickel Plating Process
Abstract
Nickel plating is one type of metal surface treatment process, which plays a role in corrosion protection, wear resistance and decoration. The process of plastic chemical nickel plating is a new kind of metal surface treatment technolo......
Phosphating Surface Treatment of Carbon Steel and Low Alloy Steel
Surface treatment of carbon steel and low alloy steel by phosphating
Abstract: Phosphating is a surface treatment technology for carbon steel and low alloy steel, which is widely used in fields such as automobile, motorcycle, bridge and building. It has the advantages of good anti-corrosion and w......
Forging Technology: Surface Treatment of Forging Dies
Surface treatments for forging dies
Forging dies have a critical role in the forging process, and before the forging process, it is necessary to carry out corresponding surface treatments for the forging dies. These surface treatments can protect the dies from wear and corrosion, ensuring their s......
Treatment before furnace charge smelting
pretreatment of OrePrior to Smelting
Pre-treatment of ore prior to smelting is a critical process in the production of metal fromores, and can significantly improve the economics of the smelting operation. The processinvolves a number of steps including crushing, grinding, and separating metal fr......
Submerged Arc Furnace (Electric Arc Furnace, Resistance Electric Furnace) Knowledge Introduction
Iron ore gas-fired furnace is a kind of hot-blast iron-making equipment that utilizes gas fuel to smelt iron ore. Under the reduction atmosphere in the furnace, iron ore pellets, lump ore and other iron concentrate materials can be directly reduced to smelt iron.
The iron ore that is needed to be......
The basic principle of phosphating - pretreatment before phosphating
Phosphating is a process in which a series of salts are applied to metal surfaces to improve their rust protection and painted surface adhesion. In order for phosphating to be effective, proper surface preparation must take place prior to its application. This includes ridding the metal surfaces o......
Continuous casting cooling water treatment
Ladle Cooling Water Treatment
Ladle cooling water is a key process for castings during production in metallurgical plants, and its water quality requirements are also very high. If there are problems such as serious scale, excessive corrosion and water quality instability in ladel cooling water, ......
The KR method successfully realized the "three removal" pretreatment of molten iron
Introduction
Hot Metal Desulfurization (HMD) is an important step in ironmaking and steelmaking. To ensure the quality of molten iron, the sulfur content must be controlled in a proper range. HMD is carried out to reduce the sulfur content of the hot metal, so as to meet the requirements of smelt......
