Claim 1
Independent Claim
143 words
IN A PROCESS FOR DEPOSITING A FIRMLY ADHERING METAL COATING OF PREDETERMINED THICKNESS BY THE DECOMPOSITION OF NICKEL CARBONYL ON AN ALUMINUM BASE, THE STEPS COMPRISING FIRST APPLYING A THIN POROUS NICKEL FILM TO THE CLEAN METAL BASE TO A DEPTH OF BETWEEN ABOUT 0.00005 INCH TO 0.00015 INCH BY CONTACTING THE ALUMINUM BASE HEATED TO A TEMPERATURE IN THE RANGE NICKEL CARTO 400* F. WITH A STREAM OF GASEOUS NICKEL CARBONYL DILUTED WITH A NON-OXIDIZING GAS, THEREAFTER HEATING SAID THINLY COATED BASE TO A TEMPERATURE IN THE RANGE OF 500* F. TO 1200* F. WHILE MAINTAINING AN ATMOSPHERE OF CO2 ABOUT THE HEATED ALUMINUM BASE, AND THEN EXPOSING SAID NICKEL COATED ALUMINUM BASE TO NICKEL CARBONYL GAS WHILE SAID BASE IS HEATED TO A TEMPARATURE HIGH ENOUGH TO DECOMPOSE SAID CARBONYL GAS AND DEPOSIT A COATING OF NICKEL OF THE DESIRED THICKNESS.
