Magnetic particle inspection is a non-destructive testing method that detects defects on the surface or near the surface of ferromagnetic materials by the accumulation of magnetic particles in the leakage magnetic field near the defe...

X-ray or γ-ray interacts with the material, and its intensity is attenuated by absorption and scattering. Images with varying degrees of blackness corresponding to the internal structure and defects of the material can be obtained on...

Ultrasonic testing refers to a method of injecting ultrasound (high frequency and short wavelength) into the casting, and then detecting the internal defects of the casting according to the characteristics of its refraction and waveform...

In the lost wax casting process, the making of the mold shell is a key process. Casting shells made of silica sol as a binder can obtain good surface and high dimensional accuracy for castings.

The impeller refers to a rotating body with blades that transmits energy to the liquid, and can also refer to the general term for the wheel disc and the rotating blades installed on it.

The alkali metal explosion cleaning process, also known as high temperature alkali metal explosion, its basic working principle is: put the casting into a caustic soda solution with a temperature of 750-800℃ and a mass concentrati...

Martensitic stainless steel refers to a type of stainless steel whose microstructure is mainly martensite. The chromium content of martensitic stainless steel is in the range of 12%-18%, and its main alloying elements are iron,...

Steel Classification according to EN 10027-2. Designation systems for steels.

Monel is the brainchild of Robert Crooks Stanley of International Nickel Corporation. It was patented in 1906 and named after the company's president Ambrose Monell. The second "L" was deleted from the metal name because i...

The foundry industry is one of the basic industries of the entire industry. Casting plays an increasingly important role in the field of modern machinery. Many metal forming parts cannot be manufactured without casting.

Nickel-based alloys have high strength and good oxidation resistance, corrosion resistance and high temperature resistance in the range of 650 to 1000°C. Nickel-based alloy is a common high-temperature resistance alloy.

As a precision casting process, the shell making is a very critical process during investment casting. The quality of the shell is directly related to the roughness and dimensional tolerance of the final casting. Therefore, it is an i...
