For the two astronauts that had just boarded the Boeing “Starliner,” this trip was really discouraging.
According to NASA on June 10 regional time, the CST-100 “Starliner” parked at the International Space Station had an additional helium leakage. This was the 5th leakage after the launch, and the return time had to be postponed.
On June 6, Boeing’s CST-100 “Starliner” came close to the International Space Station during a human-crewed flight test goal.
From the Boeing 787 “Dreamliner” to the CST-100 “Starliner,” it carries Boeing’s assumptions for the two significant markets of aviation and aerospace in the 21st century: sending out people to the sky and then outside the environment. Regrettably, from the lithium battery fire of the “Dreamliner” to the leakage of the “Starliner,” different technological and quality issues were subjected, which seemed to show the inability of Boeing as a century-old factory.

Thermal spraying technology plays a vital duty in the aerospace field
Surface fortifying and security: Aerospace cars and their engines run under severe conditions and require to face multiple obstacles such as high temperature, high stress, high speed, deterioration, and put on. Thermal splashing innovation can dramatically enhance the service life and integrity of crucial elements by preparing multifunctional finishes such as wear-resistant, corrosion-resistant and anti-oxidation externally of these parts. For instance, after thermal splashing, high-temperature location elements such as turbine blades and combustion chambers of aircraft engines can withstand higher operating temperature levels, minimize maintenance prices, and extend the general service life of the engine.
Maintenance and remanufacturing: The upkeep cost of aerospace equipment is high, and thermal spraying modern technology can swiftly repair put on or damaged parts, such as wear repair of blade edges and re-application of engine interior coverings, lowering the demand to replace repairs and saving time and expense. On top of that, thermal spraying additionally supports the performance upgrade of old parts and realizes reliable remanufacturing.
Light-weight layout: By thermally splashing high-performance coverings on lightweight substrates, materials can be provided extra mechanical properties or unique functions, such as conductivity and warmth insulation, without including way too much weight, which fulfills the urgent demands of the aerospace area for weight decrease and multifunctional assimilation.
New worldly development: With the advancement of aerospace modern technology, the needs for product performance are boosting. Thermal spraying technology can transform conventional materials right into finishings with novel residential or commercial properties, such as slope finishings, nanocomposite coverings, and so on, which promotes the study growth and application of brand-new materials.
Customization and adaptability: The aerospace field has rigorous requirements on the size, form and function of parts. The flexibility of thermal splashing technology permits finishes to be customized according to details needs, whether it is complex geometry or special efficiency requirements, which can be achieved by exactly managing the covering thickness, structure, and framework.

The application of round tungsten powder in thermal splashing innovation is mostly because of its special physical and chemical properties.
Layer uniformity and thickness: Round tungsten powder has excellent fluidity and low particular surface area, that makes it simpler for the powder to be uniformly spread and thawed throughout the thermal spraying process, thereby creating an extra consistent and thick finish on the substrate surface. This finish can supply far better wear resistance, deterioration resistance, and high-temperature resistance, which is crucial for crucial elements in the aerospace, power, and chemical markets.
Improve coating performance: Using round tungsten powder in thermal spraying can substantially boost the bonding toughness, wear resistance, and high-temperature resistance of the covering. These advantages of spherical tungsten powder are specifically important in the manufacture of burning chamber coverings, high-temperature part wear-resistant finishes, and various other applications since these parts operate in extreme settings and have incredibly high material performance demands.
Minimize porosity: Compared with irregular-shaped powders, round powders are more likely to reduce the development of pores during piling and thawing, which is incredibly beneficial for finishes that call for high securing or rust penetration.
Suitable to a variety of thermal spraying innovations: Whether it is flame spraying, arc splashing, plasma spraying, or high-velocity oxygen-fuel thermal splashing (HVOF), spherical tungsten powder can adjust well and reveal excellent process compatibility, making it simple to choose one of the most ideal spraying innovation according to different needs.
Special applications: In some special fields, such as the manufacture of high-temperature alloys, coverings prepared by thermal plasma, and 3D printing, round tungsten powder is additionally utilized as a reinforcement stage or directly comprises an intricate framework part, further expanding its application range.
