IN A PROCESS FOR TREATING A METAL SURFACE TO FORM A COATING THEREAT, TH STEPS COMPRISING IONIZING AN INERT GAS, ACCELERATING SAID IONIZED GAS INTO A DIRECTED BEAM, PASSING SAID BEAM OF IONIZED GAS THROUGH A TRANSVERSE MAGNETIC FIELD TO OBTAIN AT LEAST ONE BEAM COMPOSED OF MONOENERGETIC IONS HAVING SUBSTANTIALLY A SINGLE CHARGE AND MASS, DISPOSING SAID METAL SURFACE IN AT LEAST ONE OF SAID BEAMS OF MONOENERGETIC IONS IN TRANSVERSE RELATIONSHIP THERETO WHEREBY SAID MONOENERGETIC ION BEAM IS INJECTED INTO SAID METAL SURFACE AND COMBINES THEREWITH TO FORM SAID COATING, AND REGULATING THE ENERGY LEVEL OF SAID MONOENERGETIC BEAM WITHIN A RANGE OF 5 TO 50 KEV., REGULATING THE CURRENT LEVEL OF SAID MONOENERGETIC BEAM TO TENS OF MILLIAMPERES AND REGULATING THE BOMBARDMENT TIME OF SAID MONOENERGETIC BEAM TO CONTROL PROPERTIES OF SAID COATING.
