For the two astronauts who had simply boarded the Boeing “Starliner,” this journey was actually discouraging.
According to NASA on June 10 regional time, the CST-100 “Starliner” parked at the International Spaceport Station had another helium leakage. This was the fifth leak after the launch, and the return time needed to be held off.
On June 6, Boeing’s CST-100 “Starliner” came close to the International Spaceport station during a human-crewed flight test mission.
From the Boeing 787 “Dreamliner” to the CST-100 “Starliner,” it brings Boeing’s expectations for both major fields of air travel and aerospace in the 21st century: sending humans to the sky and afterwards outside the environment. Unfortunately, from the lithium battery fire of the “Dreamliner” to the leakage of the “Starliner,” various technical and high quality issues were exposed, which seemed to mirror the failure of Boeing as a century-old factory.

Thermal spraying innovation plays an important role in the aerospace area
Surface area conditioning and protection: Aerospace lorries and their engines run under extreme problems and require to deal with numerous obstacles such as heat, high stress, high speed, rust, and use. Thermal spraying modern technology can dramatically boost the service life and integrity of essential parts by preparing multifunctional finishes such as wear-resistant, corrosion-resistant and anti-oxidation externally of these parts. As an example, after thermal splashing, high-temperature location elements such as turbine blades and burning chambers of aircraft engines can endure higher running temperatures, decrease maintenance costs, and expand the total service life of the engine.
Maintenance and remanufacturing: The maintenance expense of aerospace devices is high, and thermal spraying modern technology can rapidly repair used or damaged parts, such as wear fixing of blade edges and re-application of engine interior layers, minimizing the requirement to replace repairs and conserving time and expense. In addition, thermal splashing likewise supports the performance upgrade of old parts and recognizes efficient remanufacturing.
Light-weight design: By thermally splashing high-performance coverings on lightweight substratums, materials can be given added mechanical buildings or unique functions, such as conductivity and heat insulation, without including way too much weight, which fulfills the urgent needs of the aerospace field for weight reduction and multifunctional integration.
New material growth: With the development of aerospace modern technology, the requirements for product efficiency are raising. Thermal splashing innovation can transform typical products right into coverings with novel properties, such as gradient coatings, nanocomposite coatings, etc, which promotes the research development and application of new materials.
Personalization and adaptability: The aerospace field has stringent needs on the size, shape and feature of components. The versatility of thermal splashing modern technology enables coatings to be personalized according to details needs, whether it is intricate geometry or special performance demands, which can be accomplished by exactly managing the finishing density, structure, and framework.

The application of spherical tungsten powder in thermal spraying modern technology is primarily as a result of its one-of-a-kind physical and chemical homes.
Coating uniformity and thickness: Spherical tungsten powder has excellent fluidity and low certain area, that makes it easier for the powder to be uniformly spread and melted during the thermal splashing process, thereby forming a more uniform and thick finishing on the substratum surface area. This coating can provide better wear resistance, rust resistance, and high-temperature resistance, which is necessary for key elements in the aerospace, energy, and chemical sectors.
Improve coating performance: The use of spherical tungsten powder in thermal spraying can substantially boost the bonding stamina, use resistance, and high-temperature resistance of the layer. These benefits of round tungsten powder are specifically crucial in the manufacture of combustion chamber coatings, high-temperature part wear-resistant finishes, and various other applications due to the fact that these components operate in extreme environments and have incredibly high product efficiency needs.
Minimize porosity: Compared to irregular-shaped powders, spherical powders are more probable to decrease the formation of pores during stacking and melting, which is incredibly useful for finishes that call for high sealing or corrosion infiltration.
Appropriate to a variety of thermal splashing modern technologies: Whether it is fire spraying, arc splashing, plasma splashing, or high-velocity oxygen-fuel thermal splashing (HVOF), round tungsten powder can adjust well and show good process compatibility, making it simple to select the most ideal splashing innovation according to various needs.
Unique applications: In some special fields, such as the manufacture of high-temperature alloys, finishes prepared by thermal plasma, and 3D printing, round tungsten powder is also utilized as a reinforcement stage or directly makes up a complicated structure component, more expanding its application range.
