Method for inspecting and refurbishing engineering components

摘要

Refurbishing used or damaged engineering components is performed using a subtractive surface engineering process to remove material from worn or damaged critical surfaces. The method involves initially performing the process on the component to remove a first quantity of material from the surfaces, inspecting the surface of the component to determine the extent of damage and subsequently further performing the process to remove a further quantity of material if necessary.

主权项

1. A method of inspecting an engineering component for subsurface damage without performing grinding, using a chemically accelerated vibratory process to remove material from worn or damaged critically dimensioned surfaces of the component, the component being a gear, shaft, bearing, piston, axle, cam, seat or seal, the method comprising:
a) disassembling the component if necessary to fully expose the worn or damaged critically dimensioned surfaces of the component; b) performing the chemically accelerated vibratory process on the component to remove a quantity of material from the surfaces; c) inspecting the surfaces of the component to determine an extent of apparent damage; and d) on the basis of the inspection, determining whether:
i. the component can be reused; orii. the component should be scrapped.
