Destructive Bond Testing (ISO 4386-2:1982) Completed for Roll Neck Bushes
K C Engineeing has completed a destructive test of the bond strength on a repaired steel roll neck bush according to ISO 4386-2 (the Chalmers test). The results shows a high quality bond satifsying ISO requirements with no defects or unbonded areas shown in the fracture area. KC Engineering has a high quality tinning and casting process and by going beyond Ultrasonic Inspection and Liquid Dye Penetrant Testing, this proves the ability of K C Engineering where it matters most – at the bond interface. Microscopical examination confirms that fracture had occurred wholly within the whitemetal which indicates that the bond is stronger than the parent material.
