SURFACE TECHNOLOGIES
PROBLEMS WE SOLVE
Component failure is usually due to a sequence or combination of events which can initiate from the design and choice of materials through to manufacturing processing and assembly including the application of heat, welding and grinding, as well as machining and distortion of the part due to bending, rolling or forging. In services conditions can also contribute to the failure of a part such as variation in temperature and environmental conditions, uneven, high or low cyclic loads or stress profile, compression, torsion and bending as well as foreign object damage. Matching the maintenance needs of the component to its operating conditions and environment is also important to reduce the effects of aging and wear.
Curtiss-Wright Surface Technologies supports every stage of the manufacturing process from design and new manufacturing, to material testing and analysis through to in service maintenance, metal repair and overhaul of components – our metal repair and component protection services increase the strength and performance of parts and reducing costs and downtime.
