Method for producing in-situ layer with increased abrasion resistance on the surface of castings made from chromium cast iron

摘要

method of manufacturing layer in situ with increased abrasion resistance on the surface of cast iron chromowego is characterized by the fact that on the surface of the recess forms of iron sulfide applied powder iron (ii) in the amount of 0.05 - 0.5 g per 1 cm2, after which bathes in the path of the form purpose of the casting is chromowym with added titanium in amounts of 0.2 - 1.0% by mass in relation to the weight of the liquid metal.while ti is in the form of u017celazotytanu, which consists of iron in amounts of 30 - 50 mass% and titanium of 50 - 70 mass%.method of manufacturing layer in situ with increased resistance to abrasion is also that directly to the weight of the formierskiej przymodelowej introduces sulfur granules or powder of 0.5 to 10% by volume in relation to the quantity of this mass, after which the form of s one purpose of the casting chromowym liquid with added titanium.
