摘要： PROBLEM TO BE SOLVED: To provide a technology which suppresses the occurrence of defective cladding and manufactures a cylinder head containing a valve seat.
SOLUTION: The manufacturing method consists of a casting process, a grinding process, a cladding process and a valve seat forming process. The casting process casts a cylinder head casting crude material 2 containing a groove for cladding in an opening peripheral edge of a suction/exhaust port. The grinding process removes a surface layer of the groove 4 with a thickness D of 1 mm or less. The cladding process clads a metal on the groove 16 having the surface layer removed therefrom. The valve seat forming process forms a valve seat by grinding the surface of the clad part. Since a metal cast product has the structure refined more as the cooling speed at casting is higher, the cylinder head casting crude material is allowed to remain the structure refined more than conventional ones on the surface layer of the cladding groove 16. Less residual oil content and water content are found in proximity to the groove 16, therefor, the occurrence of defective cladding can be suppressed.

摘要翻译：要解决的问题：提供抑制不合格包层的发生的技术，并制造包含阀座的气缸盖。解决方案：制造方法由铸造工艺，磨削工艺，包覆工艺和阀座形成工艺组成。铸造工艺在吸入/排出口的开口周边边缘铸造一个气缸盖铸造粗材料2，其中包含用于包覆的槽。研磨处理将厚度D为1mm以下的槽4的表面层除去。包层工艺在其上从其上除去具有表面层的凹槽16上的金属。阀座形成工艺通过研磨包层部分的表面形成阀座。由于金属铸造产品的结构在浇铸时的冷却速度更高的情况下更加精细化，因此允许气缸盖铸造粗材料比包覆凹槽16的表面层上的常规结构精炼得更多。残留油含量较少并且在槽16附近发现含水量，因此可以抑制不良包层的发生。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an overlay method for a cast iron base material where an overlay layer having reduced gas defects is easily and stably obtained by suppressing gasification of graphite without performing the troublesome setting of overlay conditions and pretreatment. SOLUTION: The area ratio of flaky graphite in the structure of a cast iron base material as an object for overlay is suppressed to ≤10%, and further, the maximum length of the flaky graphite is suppressed to ≤140 μm. By suppressing the area ratio of the graphite, the total amount of the gas to be generated is suppressed, and an excessive gasification preventive countermeasure is eliminated. Further, smaller the degree of reducing the dimensions of individual graphite, smaller the amount of the gas to be generated from each graphite, and thus, even if gas defects such as pinholes and blowholes are generated in an overlay layer, the size of the gas defects is small.

摘要翻译：要解决的问题：为了提供一种铸铁基材的覆盖方法，其中通过抑制石墨的气化容易且稳定地获得具有减少的气体缺陷的覆盖层，而不执行重叠条件和预处理的麻烦的设置。解决方案：将作为覆盖物的铸铁基材的结构中的片状石墨的面积比抑制为≤10％，此外，片状石墨的最大长度被抑制为≤140μm。通过抑制石墨的面积比，抑制了所产生的气体的总量，并且消除了过度的气化防止措施。此外，减小单个石墨的尺寸的程度越小，从每个石墨产生的气体的量越少，因此即使在覆盖层中产生诸如针孔和气孔的气体缺陷，气体的尺寸缺陷小。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a valve seat having sufficient abrasion resistance by segregating an Fe rich phase in an upper part of a padding layer without forming a fragilely hard Al-Fe-based intermetallic compound in the vicinity of an interface between a Cu rich phase and aluminum alloy of a lower part of the padding layer. SOLUTION: Mixed powder comprises Fe, Cu and a two-phase separate alloy element, and is supplied to the opening end of an intake port and an exhaust port in a cylinder head for an internal combustion engine. The mixed powder is melted by irradiating to the mixed powder with a laser beam by using a semiconductor laser. The valve seat 16 is formed by performing laser padding of copper group alloy powder by solidifying the melted mixed powder. At this time, the mass ratio of the Fe, the Cu and the two-phase separate alloy element in the mixed powder is set so that the Fe is 15 to 85 mass%, and the two-phase separate alloy element is, for example, 0.02 to 2.0 mass% in C and a combination of one kind or two or more kinds among 4 to 30 mass% in Cr, and Cu is a residual part.

摘要： PROBLEM TO BE SOLVED: To provide a method for inspecting a clad layer formed by laser clad processing for inspecting even the flaw caused by hard particles being internal quality other than a surface flaw such as a crack or a pinhole without performing cutting with respect to the clad layer formed by the laser clad processing performed with respect to a part made of pig iron and enhancing inspection quality.
SOLUTION: The waveform signal expressed on an X-Y plane comprising an X-axis and a Y-axis, both of which are mutually different by 90° in phase angle, by a waveform having a phase angle and amplitude is used as a detection signal obtained by subjecting the surface of the clad layer to eddy current flaw inspection and the size of the present region of the hard particles dispersed in the clad layer is measured on the basis of the amplitude of a waveform signal (7c) having predetermined shift in relation to a phase angle with respect to the waveform signals (7a and 7b) respectively corresponding to the crack and pinhole present in the surface of the clad layer.

摘要： PROBLEM TO BE SOLVED: To provide a cladding method and apparatus that, in a pre-treatment of cladding process, eliminate liquid such as oils and water infiltrated deep into a workpiece by capillary phenomenon and that prevent defects such as a gas defect or a crack into a cladding layer, without employing complicated equipment or method.
SOLUTION: Before a cladding process 40 in which each valve seat of a cylinder head is overlaid by irradiation of a laser beam, a drying process 30 is provided in which the cylinder head is dried inside by leaving it in the air for a time (15 minutes or longer) required for evaporating the liquid infiltrated inside. As a result, the liquid infiltrated deep into the cylinder head by capillary phenomenon can be eliminated, thereby preventing the defects such as a gas defect or a crack into the cladding layer.
