Laser Etching Stainless Steel Corrosion

For high speed marking laser etching is the best process for steel surfaces.

Laser etching stainless steel corrosion.

Some of the latest results of the material analysis and corrosion tests of the laser treated material are presented. You can laser mark anodized steel carbon steel die steel stainless steel or any steel alloy. In fact any method that digs markings on the surface deep or shallow will remove this layer. Laser annealing which creates marks under the surface offers the best resistance to corrosion.

Laser engraving should be used to get the most resistant marks. Laser marking of stainless steel using the pulsed fiber laser spi g3 is described in the contribution. Possibilities and limitations of steel laser marking are discussed. Many single and multi use stainless steel medical tools and devices require passivation to help them withstand corrosion and handle numerous autoclave cycles.

Laser engraving stainless steel leads to 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. After laser etching part numbers we have the instruments passivated for corrosion resistance. There is a growing need to apply identification informational and logo marks to stainless steel devices and products and these marks must meet several strict criteria which largely preclude the use of traditional non laser techniques such as printing or engraving.

Chromium oxide is formed naturally when chromium reacts with oxygen. This thin protective layer is composed of chromium oxide. Our systems optimize these products by marking them for essential tracking and identification. The conclusion drawn for their study was the surface finishing of stainless.

Laser engraving stainless steel removes an important protective layer. At the same time these parts also require laser marking for identification tracking and traceability in accordance with new unique device identification udi requirements. Because stainless steel tools must avoid corrosion they undergo passivation which is a treatment process consisting of coating metals. If we laser etch before passivation the area of laser etch corrodes after autoclaving.

Many stainless steel medical tools and devices require passivation to help withstand corrosion and handle numerous autoclave cycles. The primary material in use is stainless steel 17 4 ph heat treated to h 900 condition.
