Abstract
In a general aspect, a coating blade for application of coating color to a fibrous web can include an elongate substrate having a longitudinal edge. Within an operating zone of the coating blade intended for contact with a coating color, the elongate substrate can include a longitudinal wear-resistant deposit adjacent to the longitudinal edge. The coating blade, within the operating zone, can also include a longitudinal masking deposit adjoining the longitudinal wear-resistant deposit.

A coating blade for application of a coating color to a fibrous web, the coating blade comprising:
- an elongate substrate having a width in a width direction between a first end and a second end of the elongate substrate, and a longitudinal edge at the first end, the elongate substrate, within an operating zone of the coating blade intended for contact with the coating color, includes:
- a longitudinal wear-resistant deposit disposed on and in contact with the elongate substrate, the longitudinal wear-resistant deposit being adjacent to the longitudinal edge of the elongate substrate, the longitudinal wear-resistant deposit including a ceramic material and having a width in the width direction in a range of 1-9 millimeters;
- a longitudinal masking deposit disposed on and in contact with the elongate substrate, the longitudinal masking deposit being next to, and adjoining the longitudinal wear-resistant deposit, the longitudinal masking deposit including a polymer material;
- and
- a transition, in the width direction, between a surface of the longitudinal wear-resistant deposit intended for contact with the coating color and a surface of the longitudinal masking deposit intended for contact with the coating color, the transition being substantially flush.
A coating blade for application of a coating color to a fibrous web, the coating blade comprising:
- an elongate substrate having a width in a width direction between a first end and a second end of the elongate substrate, and a longitudinal edge at the first end, the elongate substrate, within an operating zone of the coating blade intended for contact with the coating color, includes:
- a longitudinal wear-resistant deposit disposed on and in contact with the elongate substrate, the longitudinal wear-resistant deposit being adjacent to the longitudinal edge of the elongate substrate, the longitudinal wear-resistant deposit including a ceramic material and having a width in the width direction in a range of 1-9 millimeters;
- and
- a longitudinal masking deposit disposed on and in contact with the elongate substrate, the longitudinal masking deposit being arranged next to, and adjoining the longitudinal wear-resistant deposit at a distance of 1-9 millimeters from the longitudinal edge in the width direction, the longitudinal masking deposit including a polymer material and wherein the longitudinal masking deposit is arranged rearward of the longitudinal wear-resistant deposit in the width direction and with regard to the longitudinal edge.
