and a substance of a second material positioned within the one or more openings in the framework and configured to be removable from the framework during an electrochemical reaction. ### Claim 2 (depends on 1) The screen of claim 1, wherein the second material is more anodic than the first material. ### Claim 3 (depends on 1) The screen of claim 1, wherein the screen is configured electrochemically react when exposed to an electrolyte. ### Claim 4 (depends on 1) The screen of claim 1, wherein sizes of the one or more openings vary. ### Claim 5 (depends on 1) The screen of claim 1, wherein shapes of the one or more openings vary. ### Claim 6 (depends on 1) The screen of claim 1, wherein the one or more openings create a tortuous path to fluid flowing therethrough. ### Claim 7 (depends on 1) The screen of claim 1, wherein sizes and shapes of the one or more openings are regular and repeating. ### Claim 8 (depends on 1) The screen of claim 1, wherein the framework is defined by interstices between particles of the substance. ### Claim 9 (depends on 1) The screen of claim 1, wherein the second material is selected from the group consisting of one or more of zinc, beryllium and magnesium and combinations including one or more of the foregoing. ### Claim 10 (depends on 1) The screen of claim 1, further comprising a body defining a bore within which the framework and the substance are positioned. ### Claim 11 (depends on 10) The screen of claim 10, wherein the body is made of a third material that is nearer to the first material on the galvanic chart than to the second material. ### Claim 12 (depends on 11) The screen of claim 11, wherein the first material and the third material are substantially the same. ### Claim 13 (depends on 10) The screen of claim 10, wherein the body is tubular. ### Claim 14 (depends on 1) The screen of claim 1, wherein the substance prevents flow through at least one of the one or more openings prior to its removal from the framework. ### Claim 15 (depends on 1) The screen of claim 1, wherein the screen is employable downhole and the electrochemical reaction occurs in fluid anticipated to be downhole. ### Claim 16 A method of making a screen comprising; brazing particles within a bore of a plug with a filler metal of a first material, the particles being of a second material and the plug of a third material, the second material being more anodic than either of the first material or the third material; exposing the particles, the plug and the filler metal to a fluid; allowing an electrochemical reaction to occur; and removing the particles. ### Claim 17 (depends on 16) The method of making a screen of claim 16, further comprising filling interstices defined between the particles with the filler metal. ### Claim 18 (depends on 16) The method of making a screen of claim 16, wherein the fluid includes an electrolyte. ### Claim 19 (depends on 16) The method of making a screen of claim 16, further comprising selecting the second material to be more anodic than either the first material or the third material.
