Laser Etching Stainless Steel Corrosion

Some of the latest results of the material analysis and corrosion tests of the laser treated material are presented.

Laser etching stainless steel corrosion. Evaluated the influence of the laser marking parameters the specifically pulse energy and engraving rate on the corrosion resistance of astm f139 austenitic stainless steel laser marked surface by the use of yag laser beam using of electrochemical methods. This thin protective layer is composed of chromium oxide. You can laser mark anodized steel carbon steel die steel stainless steel or any steel alloy. Chromium oxide is formed naturally when chromium reacts with oxygen.

These devices also require laser marking for identification tracking and traceability in accordance with unique device identification udi requirements. Because stainless steel tools must avoid corrosion they undergo passivation which is a treatment process consisting of coating metals. At tykma electrox our laser systems are adept at corrosion resistant laser engraving for use on various single and multi use stainless steel tools and equipment. After laser etching part numbers we have the instruments passivated for corrosion resistance.

Laser annealing which creates marks under the surface offers the best resistance to corrosion. Many single and multi use stainless steel medical tools and devices require passivation to help them withstand corrosion and handle numerous autoclave cycles. After passivation our laser etching is all but non existent. The primary material in use is stainless steel 17 4 ph heat treated to h 900 condition.

Many stainless steel medical tools and devices require passivation to help withstand corrosion and handle numerous autoclave cycles. Possibilities and limitations of steel laser marking are discussed. At the same time these parts also require laser marking for identification tracking and traceability in accordance with new unique device identification udi requirements. Laser engraving stainless steel leads to corrosion.

In fact any method that digs markings on the surface deep or shallow will remove this layer. Our systems optimize these products by marking them for essential tracking and identification. Laser engraving should be used to get the most resistant marks. For high speed marking laser etching is the best process for steel surfaces.

The conclusion drawn for their study was the surface finishing of stainless. If we laser etch before passivation the area of laser etch corrodes after autoclaving.
