Hardness Test& thickness Test

Application of Hardness Test----Necessity Increased output of engine and turbochargers result in the speed-up of material failure. Preventive inspection is necessary to avoid sudden collapse of turbocharger. HT can be used to detect the change of hardness for critical spares.

----Suitability All impellers, inducers and aluminium alloys. Can use HT after 50000 running hours for articles or when necessary.

Application of Thickness Test----turbocharger itself through the cooling water to cool the casing, suggest that casing of thickness tests
