Chromium nitride is deposited by cathodic arc plasma. Cathodic arc plasma deposition is a relatively new thin film deposition technology, which is similar to ion plating in many aspects. Advantages: high ionization rate in the emitted particle stream, and these ionized ions have high kinetic energy (40-100eV). Many advantages of ion beam deposition, such as increasing adhesion force, increasing density of states, and high reaction rate to the formation of compound films, are reflected in cathodic arc plasma deposition.

Nickel-coated graphite powder is a composite powder with graphite particles as its core and nickel metal as its outer coating. With good lubrication and corrosion resistance, nickel was evenly deposited on the surface of graphite particles from nickel sulfate ammonia complex solution by wet hydrogen reduction It was used to manufacture high temperature self-lubricating bearing materials, low friction materials, porous nickel strips, etc. Grindable sealing coatings can also be obtained by thermal spraying.
Metal powders are prepared by electrolysis atomization and ball milling. All of them are physical changes, so electrolytic manganese is manganese powder.Electrolytic manganese metal is the main material for manufacturing manganese trioxide. In addition, because of its high purity and low impurity, it is an important alloy element for producing stainless steel, high strength low alloy steel, Al-Mn alloy, copper-manganese alloy, etc.
Nickel powder is also divided into carbonyl nickel powder, uniform color, no caking and reunion, no visible inclusions. It is mainly used for coatings and plastics as conductive pigments to shield electromagnetic interference and radio frequency interference, for various high gloss decorative paints and plastics, instead of aluminium powder as anticorrosive paint in water system, etc.
Tungsten powder-like metallic tungsten is a metallic luster gray-black metal (body-centered cubic crystallization). It is the raw material for preparing tungsten processing materials, tungsten alloys and tungsten products.
Rhodium trichloride, also known as rhodium chloride, is a kind of red-brown powder, easy to deliquescence. Used in electronics, instrumentation, metallurgy and other industries, also used in electroplating operations, catalyst preparation.Rhodium trichloride trihydrate is a kind of Lewis acid, which can form various complexes with ligands.
Fe-Si-Al alloy is an alloy powder of 85% Fe, 9% Si and 6% Al, which is processed by special process and pressed into ring or E-type magnetic powder cores. It is commonly called Kool M_ u magnetic powder cores or Sendust powder in the market.
Nanometer iron oxide is a multifunctional material. When the size of iron oxide particles is small to nanometer scale (1-100 nm), the number of surface atoms, specific surface area and surface energy of iron oxide particles increase sharply with the decrease of particle size, which shows the characteristics of small size effect, quantum size effect, surface effect and macroscopic quantum tunnel effect.
Beryllium sulfate is a kind of white powder or cubic crystalline crystals, soluble in water, insoluble in organic solvents, highly toxic, and highly carcinogenic substance. It can cause dermatitis, ulcer and skin granuloma after absorption by human body. Industrial applications include beryllium salts, ceramics and chemical reagents.
The copper-holmium alloy has light red metallic luster and massive ingot shape. The content ratio is holmium (H0): 10% or 15%, and the remaining amount is mainly copper.
