Material Testing and Inspection

Chemical Analysis

Hycrome’s chemical processes and their controls
have been audited and conform to the requirements
of NADCAP AC7108 Chemical processing.

The role of the Chemistry Laboratory is to:

Maintain all the process tanks to ensure that
they remain within the range specified by our
customers and carry out tests to ensure that
coatings produced are of a consistent quality. Tests include corrosion resistance of our Alocrom and Chromic Acid Anodised coatings to the ASTM B-117 specification and micro-hardness of our chrome plate.

Periodically review the analysis methods assess their accuracy and reliability and improvements made were necessary.

Produce training programs for the operators so they understand the principles of the process they are carrying out and the importance of proper control and operation. The solution analysis and all testing are made available to operators through our internal computer system Hyper.

Support the production team to integrate new customer specifications into existing processes or when introducing a new process to ensure that all aspects of the customer specification are met.

Metallurgy

The facilities within Hycrome enable metallurgical investigations of material microstructures to ensure that these meet customer requirements. Analysis of engine run components is undertaken to assess the suitability for repair. Additionally routine adhesion testing of painting systems are undertaken as well as other general investigations.

Metallurgy services include:

Creep Life Analysis
Destructive Testing
Macro Hardness Testing
Micro Hardness Testing
Microstructure Examination
Tensile Bond Testing

Non Destructive Testing

Non Destructive Testing [NDT] is used to verify the integrity of all Aerospace and Gas Turbine engine parts, confirming to the requirements of NADCAP ACT108/1. Both newly machined and overhaul parts are cleaned at Hycrome’s Pre-Treatment Facility prior to inspection using several methods dependant on the substrate material. NDT can detect inherent defects within the material along with fatigue cracks, corrosion, pitting & defects caused by machining abuse.

This range of approved services includes:

Hardness Testing using Rockwell methods A ~ K

Acid Etch Inspection for machining abuse on ferrous and corrosion resistant materials

Magnetic Flaw Detection (MFD) for sub-surface defects

Fluorescent Penetrant Flaw Detection (PFD) of components to inspect for surface breaking defects. Level 2,3 & 4

Conductivity testing of Aluminium for detection of general machining abuse

Co-Ordinating Measuring Machine (CMM)

With an inspection plane of 1.2 m x 2.2m, a variety of simple and complex products can be measured to the tightest of tolerances.

The CMM integrates with a variety of software products to carry out inspection processes and reverse engineering.
