10、1ISO 13124:2011(E) iv ISO 2011 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each
11、 member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internationa
12、l Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards
13、 adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of
14、 patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13124 was prepared by Technical Committee ISO/TC 206, Fine ceramics.

15、 technical ceramics) Test method for interfacial bond strength of ceramic materials 1 Scope This International Standard specifies a test method for determining the interfacial tensile and shear bond strength of ceramic-ceramic, ceramic-metal, and ceramic-glass joining at ambient temperature by compr
16、ession tests on cross-bonded test pieces. Methods for test-piece preparation, test modes and rates (load rate or displacement rate), data collection and reporting procedures are addressed. This International Standard applies primarily to ceramic materials, including monolithic fine ceramics and whis
17、ker-, fibre- or particulate-reinforced ceramic composites. This test method can be used for materials research, quality control, and characterization and design data generation purposes. 2 Normative references The following referenced documents are indispensable for the application of this document.

28、ross-bonded sample is loaded in compression which yields tensile or shear stress in the interface until the occurrence of debonding in the interface. Two different forms of mounting the cross-bonded sample in a fixture are designed to measure the interfacial tensile and shear bond strength, respecti
29、vely. In the case of the former, a uniaxial tensile stress is generated when the testing sample is subjected to a compressive load, as shown in Figure 2 a). For the latter, a cross-bonded sample is loaded in compression to induce failure by shear at the interface, as shown in Figure 2 b). The test i
30、s usually performed at a constant cross-head displacement rate. The load at fracture and the bonded area are used to compute the tensile and shear bond strength.

33、speed shall be used. The testing machine shall be in accordance with ISO 7500-1:2004, Class 1, with an accuracy of 1 % of the indicated load during compression or tension tests. 6.2 Data acquisition Obtain the maximum load and at least an autographic record of the applied load versus cross-head disp
34、lacement or versus testing time. Use either analog chart recorders or digital data acquisition systems. Recording devices shall be accurate to within 1 % of the selected range of the testing equipment including the readout unit, and have a minimum data acquisition rate of 10 Hz with a response of 50
35、 Hz deemed more than sufficient. 6.3 Dimension-measuring device Micrometers and other devices used for measuring linear dimensions must be accurate to at least 0,01 mm and shall be in accordance with ISO 3611. Alternative dimension-measuring instruments may be used provided that they have a resoluti
36、on of 0,01 mm or finer. 6.4 Testing fixture The sketch of the testing fixtures is shown in Figure 3. To avoid unsymmetrical stress in the sample, the top of the pressure head is in the centre point of the pressure head, and it is arc shaped at two perpendicular directions, as shown in Figure 3 a). A
37、lternatively, a bearing ball inlayed in the centre of a rectangular pressure head can be used, as shown in Figure 3 b). Thus, a point-contact at the top of the pressure head can be realized in the compressive process. The supporting fixture shall be suitable and moveable, and the width of the groove
38、 such that the cross-bonded sample can be inserted into the fixture freely and with a smooth contact, as shown in Figure 3 c). The fixture shall remain elastic over the load ranges used. The fixture should be made of a hard metal with elastic modulus over 200 GPa and hardness (HV) over 3 GPa. The pr
39、essure head is designed for applying the tensile load in the interface during the tensile bonding strength test, not for the shear bond strength test. The weight of the pressure head should be added into the final load for calculating the strength. To avoid the unsymmetrical tensile stress, it is re
40、commended that the width of the pressure head should be equal to that of the test piece, e.g. b = b3. The parallelism tolerance on opposite longitudinal faces of the supporting fixture shall not exceed 0,01 mm, and both the upper and lower surfaces should be smooth planes. NOTE While the cross-bonde
41、d sample is put into the testing fixture, as shown in Figures 5 and 6, the inside bar would be in smooth contact with two inner surfaces of the fixture, without friction when it moves. The thickness of the pressure head should be a little smaller than the width of the groove, and the depth of the gr
42、oove in the pressure head is larger than the thickness of the bar, e.g. b3h.

44、angular section shall be prepared before bonding, as shown in Figure 4. The angles of the cross-section should be right-angles within 1. Table 2 shows the recommended dimensions of the bars with the section size of 4 mm 4 mm, and the length should be larger than 12 mm. The parallelism tolerance on t
45、he opposite longitudinal face is 0,015 mm. All of the bar samples shall not be chamfered. lhbFigure 4 Schematic illustrations of the rectangular test pieces Table 2 Recommended dimensions for cross-bonded sample and fixture Dimensions in millimetres Dimension Description Value Tolerance l b h Length

The phase compositions of the two rectangular samples can be the same or different. 7.2 Test-piece preparation 7.2.
47、1 General This International Standard allows several options for test-piece preparation. For chemical diffusion joining, the contact surfaces of the bars are polished up to at least 1200# SiC paper, and then cleaned. For strength evaluation of glues, the surface of the test piece does not need polis
48、hing. Each pair of bars that need to bond (sometimes of the same material) is joined to form a symmetrical cross, as shown in Figure 1. The technique used for joining, depending on the aims of measurement, can be chemical or physical bonding. 7.2.2 Test-piece storage The test pieces shall be handled
49、 with care to avoid the introduction of damage after test-piece preparation. Test pieces shall be stored separately and not allowed to impact or scratch each other. 7.2.3 Number of test pieces A minimum of 10 test pieces is required for the purpose of estimating the mean interfacial tensile bond strength or interfacial shear bond strength. A minimum of 30 test pieces is recommended if a statistical strength analysis (e.g. a Weibull analysis) is demanded. The use of 30 test pie
