About Ilan Lesnoy

Ilan is a chemist and process engineer with a Bachelor of Science in Chemistry from William Paterson University, and a professional background in aerospace manufacturing and metal finishing. His education provided a strong foundation in chemical principles, materials science, analytical chemistry, and process control, which he has applied throughout his career in our highly regulated manufacturing environment.

He is our dedicated plating and anodizing Engineer at our Nadcap-certified aerospace metal finishing facility, where he is responsible for developing, optimizing, and maintaining critical surface treatment processes used on aerospace components. His expertise includes standard anodizing, hard anodizing using proprietary additives, passivation, chemical conversion coatings, electroless nickel (steel and aluminum), process validation, and quality systems compliance within the aerospace industry. His experience includes monitoring bath chemistry, controlling process parameters, evaluating coating thickness and quality, troubleshooting process deviations, and ensuring compliance with aerospace specifications and customer requirements. Through process optimization and statistical analysis, he works to improve coating consistency, corrosion resistance, wear performance, and overall product quality.  In addition, he is developing our new plating on plastic line, which will be coming soon!

A significant portion of his work focuses on anodizing aluminum alloys, an electrochemical process that converts the base aluminum surface into aluminum oxide, which provides excellent corrosion resistance in highly corrosive environments. Hard anodizing is performed on various types of parts, such as landing gears, actuator systems, hydraulic systems, and parts that require a corrosion resistant, abrasive surface. Hard anodizing is done to provide a thicker coating while  at a lower temperature to prevent heat buildup and burning. The heart of Aerotech’s hard coat process is our capacitor discharge unit. This allows us to process even the most geometrically challenging parts, such as landing gears, while using minimum voltage to lower burning susceptibility.

He works closely with production, quality, and prime engineering teams to implement process improvements, reduce variability, and ensure that all finished products meet stringent aerospace standards.
