摘要
An improved inspection penetrant process employing a dyed liquid nonsurfactant-type penetrant, a remover, and a water rinse, in which the remover consists of a water solution of a nonsurfactant-type solvency accelerator which is selected from the group consisting of dihydroxybenzenes, carbamide and sodium benzoate. The penetrant, which is normally only slightly soluble in water, dissolves more readily in the solvency-accelerated water mixture, with the result that an improved removal of background porosity entrapments of penetrant is obtained, while entrapments of penetrant in crack defects are retained to a high level of entrapment efficiency.
