讲座简介：Singapore’s aviation and aerospace sectors are key drivers of domestic economic growth, reinforcing the nation’s position as a leading regional air hub and contributing about 5% to the Singapore’s GDP in 2025. Thermal spray technologies have long played an important role in aerospace’s maintenance, repair and overhaul (MRO) activities. Established processes such as Atmospheric Plasma Spray (APS), High Velocity Oxy-Fuel (HVOF), and Flame Spray are widely used for component restoration, wear protection, and thermal barrier applications. More recently, cold spray has emerged as a promising addition to the thermal spray family, attracting growing interest for aerospace applications due to its low heat input, reduced oxidation, and potential for structural repair. This presentation will introduce several projects supported under the Singapore Aerospace Programme (SAP) that employ conventional thermal spray technologies, particularly APS and HVOF. Their performance and application outcomes will be compared with equivalent coatings and deposits produced using cold spray with objects to highlight the technical advantages, limitations, and future opportunities of cold spray for wider adoption in the aerospace industry.
