THE INVENTION INVOLVES A NONRINSES TYPE HYDROPHILIC SURFACE-TREATING PROCESS CAPABLE OF IMPARTING HYDROPHILICITY TO THE SURFACE OF A METAL MATERIAL, E.G., ALUMINIUM, AND, AT THE SAME TIME, FORMING THEREON A COATING EXCELLING IN RESISTANCE TO CORROSION. IN THE PROCESS THERE IS APPLIED AN AQUEOUS SOLUTION WHICH CONTAIN IN SELECTED AMOUNTS OF CR IONS (III, V1), F, SIO2 AND A WATER-SOLUBLE ACRYLIC ACID POLYMER, AND OPTIONAL PO4-3, IF NECESSARY. AN ALUMINUM ARTICLE TREATED BY THIS PROCESS IS SUITABLE FOR THE FINS OF A HEAT EXCHANGER.
