## Abstract

A nozzle assembly may be used to apply fluid to an advancing substrate. The nozzle assembly includes a nozzle body made from a first material. The nozzle body may include one or more abrasion resistant materials fused to the nozzle body. The nozzle body may be configured to deposit a fluid, using a shim plate, onto the advancing substrate. As the substrate advances past the nozzle assembly, the substrate and/or the fluid may contact the nozzle assembly resulting in wear. The one or more abrasion resistant materials, which is different than the first material of the nozzle body, may be fused to a portion of the nozzle body to reduce the wear and prolong the life of the nozzle body. Thus, the portion of the nozzle body having the abrasion resistant material is restored rather than having to replace the entire nozzle body.

## Claims

### Claim 1

An apparatus for applying fluid to an advancing substrate, the apparatus comprising:
a nozzle body comprising a first material, wherein the first material is selected from the group consisting of: an iron based alloy, an aluminum based alloy, and a titanium based alloy, and wherein the nozzle body comprises:
a passageway;
one or more abrasion resistant materials fused to the nozzle body to form a nozzle contact portion adapted to contact the advancing substrate, the one or more abrasion resistant materials comprising a first layer comprising tungsten carbide or vanadium carbide, and a second layer comprising a nickel-based alloy; and
a shim plate connected with the nozzle body, the shim plate comprising a plurality of slots in fluid communication with the passageway.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the nozzle body comprises:
a first nozzle member; and
a second nozzle member removably connected with the first nozzle member.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the shim plate is positioned between the first nozzle member and the second nozzle member.

### Claim 4 (depends on 2)

The apparatus of claim 2, wherein the first nozzle member or the second nozzle member is free of abrasion resistant material.

### Claim 5 (depends on 2)

The apparatus of claim 2, wherein at least one of the first nozzle member and the second nozzle member comprises a nozzle contact portion.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein the one or more abrasion resistant materials comprise a depth of from about 0.5 mm to about 4 mm.
