Irradiation damage to nuclear reactor materials
Nuclear Reactor irradiation damage of materials
In the field of nuclear energy, fuel is typically composed of a mixture of U235 and U238, placed in the core of the reactor. This core is then kept in operation for a certain period of time and produces neutrons. The neutrons produced by the fission......

Technical condition of steel bar for internal combustion engine valve (GB/T 12773-1991)
Internal combustion engine valves are essential components of internal combustion engines and are the control elements for the formation of the combustion chamber volume. It is necessary to pass a certain am......
Common Defects in Heat Treatment of Bearing Parts
Common Defects in Heat Treatment of Bearing Parts
Heat treatment of bearing parts is a relatively complex and difficult process. As an important part in bearing production and processing, and an important part of most parts performance, heat treatment of bearing parts must be a quality that is cl......
How to improve the BONDING ability of electroplating
Improving Bonding Ability of Plating
The electroplating layer provides strong adhesion to the substrate and imparts corrosion resistance, wear resistance, solderability, and many other desirable properties for the treated part. Plated coatings are particularly suited for decorative finishes since......
Radiation damage and radiation effects on metals
Introduction
The study of the effects of radiation on metals has brought forth an immense variety of discoveries, which have yielded revolutionary advancements in the fields of physics and engineering. Radiation, especially in the form of gamma rays, has been known to have a myriad of effects on ......
Performance requirements for machine tool lubrication and machine oil (grease)
Periodic lubrication of machine tools is of great significance, because lack of lubrication or poor lubrication will lead to machine tool, bearing and other components to find acceleration wear and even cause machine tool failure. Therefore, it is very important to choose the most suitable lubrica......
Radiation corrosion
Radiation Corrosion
Radiation corrosion, also known as “electrochemical corrosion,” is the deterioration of metal components due to the exposure of radiation. Radiation corrosion can occur both externally and internally and is not limited to metal components, as non-metal materials can also be ......
Additives for alkaline cyanide cadmium plating baths
Introduction
Chromium plating is a popular surface plating technology used in a variety of industries. It involves the deposition of a layer of chromium or chromium alloy onto a substrate (usually metal) surface. Chromium plating is used to reduce scratches and wear, protect against oxidation and ......
hydrogen corrosion
Hydrogen embrittlement
Hydrogen embrittlement is a unique form of material degradation. It is caused by the accumulation of atomic hydrogen within a material, eventually leading to catastrophic failure and irreparable damage. It affects a wide range of materials and many structural components, an......
Effect of Hydrogen Evolution on Coating
Hydrogens Effects on Coating
Introduction
Hydrogen is a major component of the universe, and can have significant effects on its environment. In particular, the effects of hydrogen on coatings and other materials used in the production and protection of metal products can be dramatic. While hydr......
