Description
Patented Oct. 26, 1937 UNITED STATES PRODUCTION OF A PROTECTIVE IRON LAYER N Walter Enders, Solingen-Ohligs, Germany No Drawing. Application October 26, 1936, Serial No. 107,732. In Germany November 5, 1935 Claims.
A great variety of processes are known for the production of a protective layer on iron (steel), also by way of cementation, that is by heating the iron surrounded by a powder (cementation powder) in a closed container. In this cementation powder aluminium powder usually plays the chief part.
According to the present invention a partibularly heat-resisting protective layer is produced con is alloyed into the iron in a quantity which substantially affects the heat resistance. 0 A protective layer on iron (steel), produced in accordance with the invention, has proved to be particularly resistant to high temperatures (not liable to form scale), but is also capable of with standing corrosion and wear.
For the rest the processwith aluminium and silicon is carried out in the known manner. The powder consisting of aluminium and silicon is placed with the article to be cemented in a closed container and brought to a high temperature, in the case under discussion to about 1000.
The process has been tried out with aluminium and silicon, .but besides the silicon another metalloid or metal may be'added, for instance chromium, manganese, titanium or the like. An ad' v dition of metal oxides or metal salts or any other non-metallic addition is however unnecessary and may even have a disturbing effect, as for instance 5 the addition of binders.
What I claim is: Y
1. A process for the production of a protective layer on iron or steel, consisting in surrounding the iron with a powdered material consisting of 10 aluminium and silicon in a closed vessel and applying heat thereto, whereby the silicon as well as the aluminium become alloyed with the iron ,to increase the heat resistance thereof.
2. A process for the production of a protective layer on iron or steel, consisting in surrounding the iron with a mixture of powdered aluminium and powdered silicon in a closed vessel, and applying heat thereto,'whereby the silicon as well as the aluminium become alloyed with the iron to increase the heat resistance thereof.
3. A process as claimed in claim 2 wherein the silicon content of the mixture is 30 to 40%.
4. A process for the production of a protective layer on iron or steel consisting insurrounding the iron with an aluminium silicon alloy in powdered form in a closed vessel and applying heat thereto,'whereby the silicon as'.well as the aluminium-become alloyed with the iron to increase the heat resistance thereof.
5. A process as claimed in claim 4 wherein the silicon content of the alloy is to 40%.
