Passivation is a metal finishing process used to prevent corrosion.
The passivation process uses nitric acid to remove free iron from the surface. The chemical treatment leads to a protective oxide layer that is less likely to chemically react with air and cause corrosion.
PEEK is resistant to most chemicals so the etchant has to be particularly aggressive,
Using a combination of potassium chloride & concentrated sulphuric acid we are able to improve the bonding surface of the material.
Our Pressure Testing System (Air) is capable of testing a wide range of components & materials.
Molykote is an anti-friction dry film lubricant that is applied through spraying,
Once applied the components are then ‘stoved’ at a high temperature .
Bond Primers are used to improve the adhesion of structural bonds and we apply this by spraying,
A few of the more common bond primes we stock and use on a regular basis are;
EC 3960, EC 3924B, EC 2333, BR127, Redux 112 & 119
Our highly skilled paint spraying department cover a vast range of Aerospace Primers including epoxy, fuel tank and water-based primers.
We can process parts up to 2.6 metres long.
We stock and apply a vast range of Aerospace Top Coats including;
Polyurethane, Epoxy Top Coats & Acrylic coatings.
These are applied, cured and baked in one of our SprayBake booths.
Using kit form templates, we have streamlined the masking process with our experienced and skilled masking department.
This is carried out using our Inkjet part marking machine.
NADCAP Approved NDT Department includes;
Penetrant Flaw Detect (PFD) is designed to identify any surface breaking defects such as cracks, laps or porosity
The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability
We can process parts up to 2.60 metres long
Magnetic Flaw Detect (MFD)
Magnetic Particle Inspection is used to detect surface or near-surface flaws such as cracks, laps, seams and inclusions
The method is applicable to all metals which can be strongly magnetised – ferritic steels and irons, but not generally austenitic steels
We can process parts up to 900mm long
All of our NDT Technicians are Level II qualified & we have designated Level III consultant who carries out Technique Sheet & Data Card Approval, Procedure Writing, Annual Performance Reviews, Regular Audits etc.
A hardness test is a method employed to measure the hardness of a material and if the manufacturing process has affected the condition of the material,
We carry out Rockwell and Vickers Hardness Testing within our NDT department
We carry out electrical conductivity testing of nonmagnetic metals using the electromagnetic (eddy-current) method
Electrical conductivity testing can be used to determine: type of metal or alloy, type of heat treatment (in conjunction with a hardness examination), aging of the alloy, and heat damage.
Pre–penetrant etch (pre–pen etch) is a surface preparation process which primarily removes smeared material to prepare a part for subsequent Fluorescent Penetrant Inspection (FPI) processing.
There are 2 types of blasting that we carry out, these are Dry Grit Blasting and Soft Media Blasting.
Grit blasting is a process where abrasive particles are accelerated and forcefully directed against a surface. These high-speed abrasive particles remove contaminants from the material’s surface and condition the surface for subsequent finishing, whereas Soft Media Blasting is mainly used for paint removal.
Parts are fully degreased prior to further operations such as NDT,
Components are loaded into a sealed unit, and processed using solvent perchloroethylene, which is effective, safe and environmentally friendly with zero emissions to the atmosphere, complying with the very latest environmental regulations.
Chromic Acid Anodizing is an electrochemical process and is a specialist surface finish used primarily within the defence and aerospace sectors
The process gives relatively soft, thin coatings, these are used mainly for electrical insulation and general protection against corrosion, unsealed coatings are used as a ‘key’ for paints and adhesives.
We can process parts up to 2.6 metres long
Alocrom 1200 is a non-electrolytic, chromate conversion coating.
This coating has a low electrical resistance and offers excellent protection against corrosion.
We can also apply with a pen, brush or swab for smaller areas in need of repair.
SurTec 650V is a chromium free passivation process suitable for aluminium, aluminium alloys and magnesium and is fast becoming the industry standard where corrosion resistance and electrical conductivity is essential.
It has excellent bare corrosion protection, comparable to hexavalent passivation.
