Abstract

A spinner for use in manufacturing glass fibers includes a body having an upper wall with an opening therethrough, a lower wall, and a side wall extending between the upper wall and the lower wall. The side wall comprises a plurality of orifices, and the body comprises a metal alloy material and is formed using a localized welding method, such as a directed energy deposition (DED) method.

First claim

What is claimed is:

1 . A process for manufacturing a component, the process comprising:
depositing a metal alloy material onto a substrate; simultaneously applying a localized welding means to the metal alloy material as the metal alloy material is being deposited; and sequentially depositing and welding the metal alloy material into a plurality of layers to form the component, wherein the metal alloy material comprises:
chromium in an amount between 25.0 wt. % and 40.0 wt. %; and
up to 75 wt. % of nickel, cobalt, or a combination thereof,
wherein the component is a spinner for use in manufacturing glass fibers, and wherein the localized welding means is directed energy deposition.

2 . The process according to claim 1 , wherein the metal alloy material further comprises at least one of tungsten, boron, and carbon.

3 . The process according to claim 2 , wherein the metal alloy material further comprises at least one of tantalum, zirconium, and hafnium.

4 . The process according to claim 1 , wherein at least one of a power and a travel speed of a heat source are controlled in order to control a solidification rate of the metal alloy material.

5 . The process according to claim 1 , wherein the spinner has a total strain (in/in) that is at least 50% less than a total strain of a spinner made of the same metal alloy material by casting.

6 . The process according to claim 1 , wherein the spinner has a minimum creep rate (×10 −4 ) (in/in/hr) that is at least 50% lower than a minimum creep rate of an identical a spinner made of the same metal alloy material by casting.

7 . The process according to claim 1 , wherein the spinner has a corrosion penetration depth (μm) that is at least 20% lower than a corrosion penetration depth of a spinner made of the same metal alloy material by casting.

8 . The process according to claim 1 , wherein the spinner comprises a body having an upper wall with an opening therethrough, a lower wall, and a side wall extending between the upper wall and the lower wall, the side wall comprising a plurality of orifices.

9 . The process according to claim 1 , wherein the metal alloy material comprises:
chromium in an amount between 25.0 wt. % and 40.0 wt. %; nickel in an amount between 15.0 wt. % and 25.0 wt. %; cobalt in an amount between 25.0 wt. % and 39.0 wt. %; tungsten in an amount between 0.01 wt. % and 10.0 wt. %; boron in an amount between 0.002 wt. % and 0.05 wt. %; carbon in an amount between 0.1 wt. % and 1.0 wt. %; tantalum in an amount between 0.01 wt. % and 5.0 wt. %; zirconium in an amount between 0.1 wt. % and 0.4 wt. %; and hafnium in an amount between 0.01 wt. % and 1.0 wt. %.

10 . The process according to claim 1 , wherein the metal alloy material exhibits an anisotropic grain structure in the spinner having columnar dendritic regions with an average grain size between about 50 μm and about 200 μm when measured across the width of the grain.

11 . The process according to claim 1 , wherein the metal alloy material exhibits an anisotropic grain structure in the spinner having columnar dendritic regions with an average grain size between about 20 μm and about 200 μm when measured along the grain.
