Patent number: 6955209Abstract: A method and arrangement for implementing post-heat treatment after spray forming is ended to achieve stress control in the manufacture of a spray formed metallic tool involves providing a spray-formed metallic tool by applying a spray-forming material on a mold substrate and causing substantially homogenous metallic phase transformations of the spray forming material within the spray-formed metallic tool to a substantially homogenous distribution of commingled metallic phases consisting, for example, of predetermined proportions of at least a bainite phase and a martinsite phase.Type: GrantFiled: November 27, 2001Date of Patent: October 18, 2005Assignee: Ford Motor CompanyInventors: Richard L Allor, Allen Dennis Roche, Samir Samir

Patent number: 6923241Abstract: Method and apparatus for controlling stresses in a spray form process makes use of one dimensional modeling in which characteristics of a geometrical point are quantified by iterative detection, such as taking a surface temperature reading using a pyrometer. This temperature information is used in a one dimensional simulation to predict characteristics for a column from the point down through a spray-formed article to an interface with a substrate. The modeling technique can used with a plurality of geometrical points to model the whole article, and the one dimensional simulation can be integrated with robotic spray-forming controls to minimize residual stress in the spray-formed article.Type: GrantFiled: November 27, 2001Date of Patent: August 2, 2005Assignee: Ford Motor CompanyInventors: Allen Dennis Roche, Samir Samir, Chijoke Mgbokwere, Mark Lusk

Patent number: 6904950Abstract: Method and apparatus for controlling a spray-forming process incorporating time, temperature, and transformation dependent stress relief techniques involves the manipulation of both temperature and time for strategic phase changes that result in a specific and planned volumetric increase. This manipulation is made based on controlling ongoing spray parameters to spray-form an article having a mixed-phase and interspersed makeup of metallic phases that minimizes residual stress in the article.Type: GrantFiled: November 27, 2001Date of Patent: June 14, 2005Assignee: Ford Motor CompanyInventors: Allen Dennis Roche, Samir Samir, Chijoke Mgbokwere, Mark Lusk

Method and arrangement for implementing heat treatment during the execution of spray-form techniques
Patent number: 6883581Abstract: A method for implementing post-heat treatment during spray forming to achieve stress control in the manufacture of a spray formed metallic tool involves applying a metallic spray-forming material onto a mold substrate and causing substantially homogenous metallic phase transformations from the austenite phase, for example, via manipulation of either or both of the substrate temperature and the spray forming cell environment temperature.Type: GrantFiled: November 27, 2001Date of Patent: April 26, 2005Assignee: Ford Motor CompanyInventors: Allen Dennis Roche, Samir Samir, Chijoke Mgbokwere, Mark Lusk -
Patent number: 6805188Abstract: A method for implementing pre-heat treatment before spray forming begins to achieve stress control in the manufacture of a spray formed metallic article involves preheating either or both of a spray forming cell environment and a mold substrate, initiating application of the metallic spray forming material onto the mold substrate, and causing substantially homogenous initial metallic phase transformations from the austenite phase via a predetermined relationship between the initial application temperature of the spray-forming material and the initial temperature of either or both of the preheated cell environment and the preheated mold substrate.Type: GrantFiled: November 27, 2001Date of Patent: October 19, 2004Assignee: Ford Global Technologies, LLCInventors: Allen Dennis Roche, Joseph A.

Patent number: 6796366Abstract: One method of the present invention includes introducing a slurry into a mold unit comprised of a mold contained within a casting receptacle and lowering the temperature of the slurry to freeze the slurry and form a freeze-cast substrate while controlling temperature gradients within the mold unit to minimize distortion in the freeze-cast substrate. Another method includes introducing a slurry into a mold unit comprised of a mold contained within a casting receptacle, placing insulation material around at least a portion of the casting receptacle to minimize distortion in the freeze-cast substrate by controlling temperature gradients within the mold unit, and lowering the temperature of the slurry to freeze the slurry to form a freeze-cast substrate.Type: GrantFiled: October 30, 2002Date of Patent: September 28, 2004Assignee: Ford Motor CompanyInventors: Allen Dennis Roche, John Michael Nicholson, Richard L.
