DLyte surface finishing for aerospace and energy industries

Surface finishing operations play an extremely important role in the manufacturing of aerospace and energy components, since it helps to improve efficiency, while increasing reliability and durability. Parts used in those sectors must withstand high stress corrosive conditions, high loads with long-term lifespan and meeting demanding cycle life specifications.

Accuracy, traceability and industrial-grade control are extremely necessary to achieve prescribed requirements, since the main part of production is subordinated to the security and to the full implementation of the technological process.

DLyte performs effective surface finishing of unusual and very hard metals and alloys as titanium, aluminum and nickel alloys commonly used in aerospace and energy sectors to better respond to fluctuations in temperature.

Leading Original Equipment Manufactures (OEM) and contract organizations in the energy and aerospace supply chain rely on our technology to automate surface finishing tasks with stable, repeatable and traceable results which improve conventional surface finishing processes.

Since years liquid electropolishing has been used as the final step of production to improve cycle life and prevent premature part failures. Dry electropolishing replaces several finishing steps, including liquid electropolishing as it removes effectively roughness and burrs from the parts and enhance corrosion resistance in one step.

The company produces equipment and consumables in compliance with the ISO 9001:2015 quality management system to meet the most demanding international standards, ensuring quality and safety of parts, as well as cost-effective process.


DLyte precisely surface smooths, deburrs and passivates parts made from any manufacturing method, including forging, casting, machining, additive manufacturing in the aerospace industry.

Common applications are engine components, fasteners, heat exchangers, solar panels, pressure vessels, turbine blades and stators, blisks, guide vanes, bearings and gear boxes, structure components, airfoils, wiring, valves and pipes, steam boilers and steam turbines.

DryLyte’s key technical advantages for aerodynamic applications include:

  • Extremely low and homogeneous roughness finishes (Ra under 0.05 microns)
  • Geometry preservation with no edge rounding
  • Show surface design flaws
  • Increased resistance to corrosion (30 times more than passivation)
  • Improved aerodynamics, reducing fuel consumption
  • Increased part durability
  • Faster and absolutely reliable and traceable processes

Common materials

01. Nickel alloys

It can be easily alloyed with other metals and alloys, including nickel brasses, bronze, copper, chrome, aluminum, cobalt, silver, and gold. Its alloys have outstanding resistance to corrosion and high-temperature scaling, exceptional high-temperature strength, shape memory, and low coefficient of expansion.

02. Titanium

An appealing and popular material that can be alloyed with iron, aluminum and vanadium, among others, to produce strong and lightweight alloys. Its most useful advantages are corrosion resistance, strength-to-density ratio, biocompatibility, durability, and hypoallergenic and aesthetically attractive properties.

03. Carbon Steel

An alloy made of iron and carbon. Its properties are mainly defined by the amount of carbon it has, determining the hardness, ductility, and tensile strength of the steel. The strength and durability of carbon steel make it suitable for many industries, as it withstands higher levels of wear and tear.

04. Aluminium

This is the most widespread metal on Earth. Aluminum is light, robust, durable, and functional, and one of the most common engineering materials of our time. It is widely used in the jewelry, automotive, aerospace and energy industries due to its main benefits: corrosion resistance, recyclability, and cost efficiency.
