Abstract
The utility model relates to a metal groove barrel. One layer of titanium nitride or a titanium carbide layer is planted on the surface of the metal groove barrel, which increases the abrasive resistance of the groove barrel and extends the service life of the groove barrel.
Description
The utility model relates to a kind of metal drum.
Groove drum is the textile workpiece that a kind of at high speed rotation is in running condition.Metal drum divides steel plate groove drum, cast iron grooved drum and cast aluminium groove drum etc., has occurred a kind of superplastic grooved alloy drum recently again.For hardness and the resistance to abrasion that increases the groove drum surface, to prolong the service life of groove drum, generally to carry out chromium plating on above-mentioned groove drum surface and handle, both there was the chromium plating Structural layer on the groove drum surface.The shortcoming of this chrome-plated metal groove drum is that resistance to abrasion is still lower, in addition because the restriction of chrome-plated process, surface plating in the groove on groove drum surface is incomplete, even do not plate chromium, this just makes the groove drum superficial hardness differ, resistance to abrasion has poor tool, and the life-span of groove drum is that this has just reduced the life-span of groove drum in the low surface damage of resistance to abrasion.
The purpose of this utility model be to improve the shortcoming of prior art and provide that a kind of resistance to abrasion is good, surperficial titanium-nitride that the life-span is long or the metal drum of titanium carbide.
The purpose of this utility model is achieved in that on the surface of metal drum and has made it one deck titanium nitride layer or titanium carbide layer through being coated with.This titanium nitride layer or titanium carbide layer not only can exist in the surface of groove drum, and can exist in the surface in the groove drum groove, make the outside face coating of whole groove drum even, and titanium nitride layer or titanium carbide layer be than chromium coating hardness height, and resistance to abrasion is good.
The utility model superficial hardness height, resistance to abrasion are good, thereby the life-span is long.
Be described as follows by embodiment below in conjunction with accompanying drawing:

On the surface of the cylindrical shell 1 of the metal drum that is shaped on the double helix groove, made it one deck titanium nitride layer 2 through being coated with.
Embodiment 2
On the surface of the cylindrical shell 1 of the metal drum that is shaped on the double helix groove, made it one deck titanium carbide layer 2 through being coated with.
Claims (1)
1, a kind of metal drum is characterized in that on the surface of metal drum one deck titanium nitride layer or titanium carbide layer being arranged.
