The piezoelectric ceramic coating, [0.94(Bi0.5Na0.5)TiO3-0.06BaTiO3]0.98-(LiNbO3)0.02 (BNBTLN), was fabricated by thermal spray process on stainless steel substrates with thermal barrier coating (TBC) as an intermediary layer. The morphology, structure, and electrical properties of the thermal-sprayed BNBTLN coatings after furnace heat treatment (F-HT) and plasma torch heat treatment (P-HT) were studied, respectively. The BNBTLN coatings after F-HT […]

Silicon carbide hot surface ignition has been used in gas-powered equipment for decades because it delivers consistent ignition in environments defined by heat, thermal cycling, and combustion byproducts. In appliance applications — where ignition must be repeatable, safe, and manufacturable at scale — silicon carbide remains the baseline material against which other igniter technologies are […]

Laser powder bed fusion is a common additive manufacturing process in which metal powder is selectively melted by a laser. Meandering stripe hatching is often used in conjunction with constant process parameters such as laser power and scan speed. However, the exposure strategy and the part geometry influence the resulting melt pool. To compensate for […]

AISI 4140 steel is one of the important categories in the steels with a wide range of applications including but not limited to automotive, general machinery, and the oil and gas industry. In the current study, an effort is made to understand the effects of heat-treatment parameters, such as heat-treatment temperature and holding time, on […]

Industrial combustion systems remain at the heart of process heating across manufacturing, energy generation, and infrastructure. As energy prices fluctuate and environmental standards tighten, burner technology has quietly evolved into a high-precision field where control, safety, and sustainability must coexist. In the U.K. and across Europe, companies such as Dunphy Combustion have spent decades refining […]

High-temperature insulation is a critical component in industrial thermal processing, maximizing efficiency, reducing energy costs, and extending equipment lifespan. As industries seek increasingly effective solutions, the demand for specialized thermal insulation is growing rapidly. This article will explore the benefits of high-temperature insulation, focusing on ceramic fiber products. It will analyze their properties, key applications, […]

Deep cryogenic treatment has been reported to be a beneficial process for improving the properties and microstructure of steels. Generally, deep cryogenic treatment should be combined with tempering to achieve the optimal effects on steels. However, the microscale relationship between deep cryogenic treatment and subsequent tempering is unclear. Therefore, the effects of deep cryogenic treatment […]

Discoloration in vacuum heat treatment can indicate contamination, leading to potential product quality issues and process inefficiencies. Even minor contamination can compromise part integrity, causing oxidation, residue buildup, and surface defects. This article explores the key sources of contamination in vacuum furnaces, including outgassing, backstreaming, leaks, and particle generation. Learn how to identify, evaluate, and […]
