POWDER METAL SCROLLS AND SINTER BRAZING METHODS FOR MAKING THE SAME |
摘要 |
<p>Methods of forming scroll compressor components are provided. The methods include forming at least one component of a scroll member from a powder metallurgy technique and joining the component with another distinct component via a sinter-brazing process. For example, a baseplate having a spiral scroll involute is joined to a hub via a joint interface having brazing material to form a braze joint with superior quality. At least one component is formed from a powder metal material including carbon and at least one species that reacts with or binds carbon to prevent migration during brazing of the sinter-brazing heat process. Optionally, during the powder metallurgy process, an alloy with a lower concentration of carbon is selected, which may be incorporated into a crystal structure with the species that prevents carbon migration.</p> |
