Abstract
A detoning blade including a steel member of stainless steel or carbon steel having a length, a width, and a thickness and a coating including titanium nitride or tungsten carbide having a thickness ranging from 0.1 microns to 4 microns or a coating of diamond embedded chromium having a thickness ranging from 2.5 microns to 7.5 microns.
Claims22
A detoning blade comprising:
- a steel member comprising at least one of carbon steel grade 1095 and stainless steel, the member having a length, a width, a surface, and a thickness;
- and
- a coating comprising tungsten carbide disposed on at least a portion of the surface of the steel member defining a layer;
- wherein the coating has a thickness ranging from 0.1 micron to 4 microns.
A detoning blade comprising:
- a steel member having a length, a width, and a thickness;
- and
- a coating comprising diamond embedded chromium on at least a portion of the steel member;
- wherein the coating has a thickness ranging from 2.5 microns to 7.5 microns and a surface hardness up to 90 Rockwell C.
A method of making a detoning blade comprising:
- providing a steel member having a length up to 40 mm and a thickness up to 100 microns;
- and
- applying a coating ranging from 0.1 micron to 7.5 microns on at least a portion of a surface of the steel member, the coating including at least one of titanium nitride, tungsten carbide, and diamond embedded chromium.
An apparatus for removing particles from a surface of a roller, comprising:
- a housing defining an open ended chamber;
- a roller rotatably mounted in said housing;
- a detoning blade having a length, a width, a thickness, a free end and a fixed end, the free end being in contact with the roller, the detoning blade comprising a steel and a coating thereon having a thickness ranging from 0.1 micron to 7.5 microns disposed on at least a portion of the steel, the coating including at least one of titanium nitride, tungsten carbide, and diamond embedded chromium;
- and
- a detoning blade holder coupled to the housing on one end and coupled to the fixed end of the detoning blade on another end of the detoning blade holder, the free end of said detoning blade contacting the roller.
A method for removing particles from a surface of a roller, comprising:
- providing a roller having a surface;
- providing a detoning blade having a length, a width, a thickness, and a free end in contact with the roller, the detoning blade comprising a steel and a coating having a thickness ranging from 0.1 micron to 7.5 microns disposed on at least a portion of the member, the coating including at least one of titanium nitride, tungsten carbide, and diamond embedded chromium;
- supporting the detoning blade in a detoning blade holder;
- applying a force on the roller using the free end of the detoning blade;
- and
- rotating the roller and scraping toner from the surface.
