Effect of Aluminizing Process on The Mechanical Properties of Stainless Steel Type (305)


The aim of this work is to study the thermal surface treatment by Aluminizingprocess of stainless steel (305) to modify the mechanical properties of the surfaceby pack cementation process. The coating process was done with various periodsof time (2, 4, 6, 8, 10) hours and temperatures (900 1000 1100)°C. The resultsshowed that the thickness of coating layer was increased with the increment oftime and temperature. The microhardness values of coating layer was reducedfrom the outer surface to the core, also the results showed that the highestmicrohardness of the coating was obtained at period of (6) hours and temperatureof (900, 1000, 1100)°C, also the highest bending stress was obtained at the periodof (6) hours and at all temperature.
