Doctor blade

A process for producing a doctor blade, comprising the steps of electrolessly depositing a first coating on the basis of a nickel-phosphorus alloy with hard material particles dispersed therein on a working edge region of the doctor blade, which is formed in a longitudinal direction of a flat and elongated main body, and electroplating a second coating on the basis of nickel at least on the first coating using an electroplating process at least on the first coating wherein during the electroplating process in the second step, firstly a base layer consisting essentially of nickel is deposited at a pH of less than 1.5 and in that this is followed by the deposition of a top layer consisting of nickel using saccharin at a pH of 2-5.

A doctor blade, in particular for doctoring off printing ink from a surface of a printing form, comprising a flat and elongated main body having a working edge region formed in a longitudinal direction, wherein the working edge region is covered with a first coating on the basis of an electrolessly deposited nickel-phosphorus alloy, and wherein hard material particles are dispersed in the first coating, wherein the first coating is covered with a second coating on the basis of electrodeposited nickel, thereby providing said first coating of nickel-phosphorus alloy covered by said second coating of nickel that comprises a nickel-phosphorus alloy, wherein said second coating comprises a base layer, which adjoins the first coating and consists essentially of pure nickel, and a top layer arranged thereabove, wherein the thickness of the base layer measures 0.2-0.8 μm, and wherein the top layer contains at least one of a saccharin or a saccharin salt.
