摘要： A coating bath containing sodium and/or potassium silicate is stabilized and its useful life prolonged by the additions of sodium or potassium hydroxide in amounts at least substantially equal to that required to compensate for the amounts of CO.sub.2 or CO.sub.3 anions introduced into the bath which, in reacting with the hydroxide formed by the hydrolysis of the silicate to form carbonates, upsets the hydrolysis equilibrium leading to further hydrolysis of the silicate. Similarly, a quantity of hydroxide is added to compensate substantially for other reactive species which significantly affect the hydrolysis equilibrium of the silicate.

摘要： Closed-loop metal powder management methods for additive manufacturing. Virgin metal powder is provided in a closed powder container comprising at least one sensor, tracker, or optical device. The metal powder is transferred to an additive manufacturing system, a portion of a metal powder layer is consolidated, and excess metal powder is transferred from the additive manufacturing system to the powder container, a second powder container, or an internal powder container. Virgin metal powder or a second metal powder are added to the excess metal powder, a quality of the mixed powder is validated, the process is repeated at least once, and powder physical transfer data associated with at least one of the steps is collected and stored in a data repository. Powder material parameters may be measured and assessed, and may be also be stored in the data repository.
