Passivation" title="Passivation

Protect your stainless steel parts against potential rust with Sharpertek’s line of passivation process solutions. During the manufacture of stainless steel iron particles become embedded in the surface of the metal. These particles can lead to rust, according to ASTM A380 Standard "Passivation is the removal of exogenous iron or iron compounds from the surface of a stainless steel by means of a chemical dissolution, most typically by a treatment with an acid solution that will remove the surface contamination but will not significantly affect the stainless steel itself."

Ultrasonic passivation offers superior rust inhibition as compared to antiquated dip tank methods. Ultrasonic cavitation allows micro-scrubbing of the outer layer of the material, used in conjunction with passivation chemistry, to remove any possibility of oxidation of the stainless steel.   

Utilization of Sharpertek’s breadth of industry knowledge allows an optimal process to be transferred to the customer. Sharpertek offers a full line of options to meet your passivation process demands; from fully automated multi-tank ultrasonic passivation to single tank multi-function passivation, and even a line of conveyor type spray wash passivation Sharpertek delivers consistent and efficient process optimization. Reduce your labor, inventory, cycle time, and MTBF with a fully automated ultrasonic passivation system by Sharpertek.
