The air hole is one of the common defects of titanium alloy bar casting. The size of a single air hole is generally no more than 2-3mm, and the small one can reach the micron or submicron level that is invisible to the naked eye. Pores are one of the sources of cracks in castings, […]
Ordinary annealing is also called industrial annealing. The retarding temperature is equivalent to the recrystallization starting temperature of similar deformed titanium alloy rods. The recrystallization temperature of some domestic brands of cast titanium rods and titanium alloy rods. At this time, the structure of the alloy has a certain diffusion activation energy. In order to […]
After sandblasting, the titanium alloy castings must be pickled before surface quality inspection. Before delivery, it is also best to carry out a pickling process so that the surface of the casting is clean and bright, which is convenient for judging the appearance quality and level of the casting. Hydrofluoric acid is the main component […]
There are many factors influencing the whiteness of titanium dioxide, including the influence of mineral sources, as well as the influence of equipment and key technologies. Through experiments and field experience, the main factors affecting its whiteness are: hydrolysis quality, removal of impurity elements and calcination conditions. The hydrolysis technology of titanium dioxide currently has […]
1. Efficient resin recovery technology Ion exchange resin (hereinafter referred to as resin) is poisoned by harmful impurities such as iron, organic matter, suspended matter, siliceous, microorganisms, heavy metals, etc. during the use process, and the resin is poisoned. These impurities cannot be completely removed by conventional methods, resulting in The exchange capacity of the […]
The dual-phase titanium reactor is mainly used in the state of heat strengthening. However, the high strength of the titanium reactor is not always maintained in the component. First of all, this is because the plasticity of the welded joint is reduced after heat treatment strengthening. Secondly, due to the poor hardenability of titanium reactors, […]
The existence of defects in titanium forgings may affect the processing quality or processing quality of subsequent processes, and some seriously affect the performance and use of titanium forgings, and even greatly reduce the service life of the manufactured parts and endanger safety. Therefore, in order to ensure or improve the quality of titanium forgings, […]
Titanium sheet is widely recognized for its advantages such as high strength, light weight and good structural rigidity. The high-strength titanium alloy Ti-6Al-4V can be used not only in the aviation field, but also as an important candidate material for structural parts in other industrial fields such as automobiles and chemicals. The formability of Ti-6Al-4V […]
In recent years, the vapor deposition technology has developed rapidly, and the vacuum plating process is one of them. Among many vacuum-plated metal and non-metal coatings, the titanium nitride film is most widely used for its high hardness, wear resistance, corrosion resistance and good decorative properties. The defective film layer in mass production should be […]
Due to the poor casting performance of titanium, the setting of the casting channel of the titanium casting mold is particularly important. If the casting channel is cast vertically according to the method of casting cobalt-chromium alloy and stainless steel, incomplete casting often occurs. The casting channel for casting titanium investment mold has the following […]
