Abstract
In the present work pure and doped ZrO
with (Al and Co 5wt%) thin film has
been deposited on stainless steel 304 substrates by spray pyrolysis technique .The film
microhardness, wear resistance, and the corrosion at different acids and alkaline are
studied . The results are proved that the microhardness and wear resistance were
improved after doping specially with (Co).The microhardness of the films has been
improved from( 927 Kg/mm
2
) for pure ZrO

2
film to(1095 Kg/mm

) 5 wt% of Co .
Wear resistance has been improved from (10*10
-10

) for pure ZrO
g/cm ) after doping with Co. Loss of weight by corrosion was decreased after
coating and doping .
