Magnetic Particles

Magnetic Particles . As mentioned previously, the particles that are used for magnetic particle inspection are a key ingredient as they form the indications that alert the inspector to defects. Particles start out as tiny milled (a machining process) pieces of iron or iron oxide. A pigment (somewhat like paint) is bonded to their surfaces to give the particles color. The metal used for the

Magnetic nanoparticles: preparation, physical properties

21.02.2012Highly magnetic materials such as cobalt and nickel are susceptible to oxidation and are toxic these authors describe a two-step size sorting process in order to obtain significant amounts of nanometric monosized particles with diameters between typically 6 and 13 nm. As the surface of the latter is not modified by the size sorting process, usual procedures are used to disperse them in

The Origin And Effect Of Magnetic Fields In EB Welding

Magnetic fields may also arise when dissimilar metals are welded. These are caused by large thermoelectric currents which are established in the joint due to the existence of a hot junction at the welding zone and a cold junction along the joint face. A thermoelectric current model is proposed to explain the generation of magnetic fields which cause the observed curved fusion zones. Tests

Direct Imprinting Using Magnetic Nickel Mold and

This nickel mold was used as the mold for magnetic embossing to imprint hot plastic polymethylmethacrylate (PMMA). The result showed that through gas-assisted hot embossing molding and electroforming, molds with high costs and complicated production processes can be massively replicated, and the replication precision is good. Through electroforming, the casting duration of magnetic nickel

Magnet

A magnet is a material or object that produces a magnetic field.This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.. A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field.

Nickel metallurgy

Nickel is a very scarce material, which must be replaced by other less expensive and more readily available materials wherever possible. The processing of nickel ores is accompanied by the evolution of toxic gases containing SO 2 and frequently As 2 O 3. A very toxic material is CO, which is used in the nickel refining process by the carbonyl

How Neodymium Magnets are Made

In practice, the actual chemical reaction used can be more complicated. A commonly used reaction is: 57 Fe + 8 B + 10 Fe 2 O 3 + 7.5 Nd 2 O 3 + 52.5 Ca- Nd 15 Fe 77 B 8 + 52.5 CaO. Vacuum Induction Furnace. Note that the powder formed by this reaction is slightly different than the Nd 2 Fe 14 B ratio. Magnets are often made both Nd-rich and B-rich, where finished magnets typically contain non

processing of nickel

Nickel processing preparation of the metal for use in various products Although it is best known for its use in coinage nickel (Ni) has become much more important for its many industrial applications which owe their importance to a unique combination of properties The Agata Nickel Processing Project site is located in a 4 995-hectare Mineral Processing Sharing Agreement (MPSA) area located in

mining process of nickel

Nickel is a silvery-white metal with a slight golden tinge that takes a high polish. It is one of only four elements that are magnetic at or near room temperature, the others being iron, cobalt and gadolinium.Its Curie temperature is 355 C (671 F), meaning that bulk nickel is non-magnetic above this temperature.

ISO 15726:2009(en), Metallic and other inorganic coatings

In the case of zinc-nickel alloys, proprietary acid and alkaline electroplating processes exist that yield deposits with controlled nickel contents. Zinc-nickel coatings containing either 8 % or 12 % nickel are most widely used, and are often considered possible substitutes for cadmium coatings. Zinc-nickel alloy coatings can reportedly be applied by brush electroplating techniques.
