    Surface modification methods and applications of aluminum powder

    Aluminum powder is a commonly used filler, widely used in fields such as thermal interface materials and industrial coatings. However, traditional aluminum powder has problems such as high viscosity, poor dispersibility, and poor thermal stability, which limit its effectiveness in some special applications. To address these issues, researchers have carried out many modification methods to improve ...

    Application of boron nitride lubricant in forging process

    In recent years, there has been a trend of oil-based lubricants being replaced by water-based lubricants. Boron nitride coatings are often used in forging nickel based alloys, high melting point alloys, and titanium machined parts, which not only provide lubrication but also prevent workpiece oxidation. Characteristics that forging lubricants should possess 1. Evenly moisten the surface to prevent...

    How to characterize the dispersion effect of powder

    (1) Particle size characterization Particles disperse in liquid to form a suspension system. The smaller the particle size and the more stable it becomes over time, the better its dispersion and less likely it is to agglomerate. Particle size characterization is commonly used to characterize the particle dispersion before and after surface modification. The better the dispersion of particles, the ...

    What are the factors that affect the specific surface area of powders

    The specific surface area of a powder is an important physical property, which refers to the total surface area (in square meters) of an oxide powder per unit mass (in grams). The size of the specific surface area is related to factors such as particle size, shape, and porosity of the powder. Generally speaking, the smaller the particles and the higher the porosity, the larger the specific surface...
