Abstract
Turbochargers experience tensile loads due their high rotational speeds. These tensile loads tend to expand surface defects present about a bore portion of a compressor wheel. Expansion of these surface defects may ultimately result in failure of the compressor wheel. Removing these surface defects or imparting residual compressive stresses on the bore portion reduces failure of the compressor wheel caused by tensile loading.
