Electrochemical Environmental Testing Device

Abstract

An electrochemical environmental testing apparatus includes a tank defining a test space suitable for containing an electrolyte solution, a base disposed in the test space, a plurality of test piece holders, and a connecting unit electrically connected to the test piece holders. The base includes a base plate with two electrode slots and two support blocks fixed to the base plate, spaced apart from each other and defining a test channel. Each support block has a plurality of spaced grooves, with two corresponding grooves of the support blocks forming a mounting area. The test piece holders are respectively mounted in the mounting areas, and each test piece holder has a placement area suitable for placing a test piece. The connecting unit includes a plurality of connection ports respectively corresponding to the test piece holders and used to enable the test piece in the test space to form an electrochemical circuit.

Claims

1. An electrochemical environmental testing apparatus, comprising: a tank defining a test space suitable for holding an electrolyte solution; a base disposed in the test space, including a base plate having two spaced-apart electrode slots, and two support blocks fixed to the base plate spaced apart and defining a test channel extending along an axis, each support block having a plurality of grooves spaced apart in a direction parallel to the axis, two grooves of the support blocks corresponding to each other in a direction perpendicular to the axis forming a mounting area; a plurality of test piece holders respectively mounted in the mounting area, each test piece holder having a placement area suitable for placing a test piece; and a connecting unit electrically connected to the test piece holders, including a plurality of connection ports respectively corresponding to the test piece holders and used to enable the test piece in the test space to form an electrochemical circuit.

2. The electrochemical environmental testing apparatus as described in claim 1, wherein, The base is detachably mounted at the bottom of the tank.

3. The electrochemical environmental testing apparatus as described in claim 1 or 2, wherein, The base is made of insulating material.

4. The electrochemical environmental testing apparatus as described in claim 1, wherein, Each of the test piece holders includes two placement portions respectively positioned in the grooves and spaced apart to form the placement area, two extension portions respectively extending upward from the placement portions, and a connecting portion connected to the top of the extension portions.

5. The electrochemical environmental testing apparatus as described in claim 4 further comprises a plurality of force-applying mechanisms respectively disposed on the test piece holders, wherein, Each of the force-applying mechanisms includes an operating member that passes through the connecting portion of the individual test piece holder and is capable of moving vertically in the longitudinal direction, and a pushing member connected to the operating member and adapted to cause the test piece placed in the individual placement area to exhibit a bending curvature due to the movement of the operating member.
