摘要： An article comprising a first portion which is formed porously by sintering of an alloy or cermet material and a second portion which is formed of a metal and intimately bonds to the first portion. For example, the article is a rocker arm for an automotive internal combustion engine, in which first portion is the wear-resistant tip portion and the second portion the body portion. The second portion is formed by molten metal forging, with the sintered first portion set in the mould as an insert, such that the molten metal under pressure is forced to infiltrate into the pores of the sintered first portion at least in a region contiguous to the interface between the first and second portions. This article features very high strength of the bond at the interface between the first and second portions.
摘要翻译：一种制品，其包括通过烧结合金或金属陶瓷材料而形成的第一部分和由金属形成并与第一部分紧密结合的第二部分。例如，该物品是用于汽车内燃机的摇臂，其中第一部分是耐磨尖端部分，第二部分是主体部分。第二部分由熔融金属锻造形成，其中烧结的第一部分作为插入件设置在模具中，使得在压力下的熔融金属至少在与第一部分相邻的区域中被迫渗透到烧结的第一部分的孔中第一和第二部分之间的界面。本文在第一和第二部分之间的界面处具有非常高的粘合强度。

摘要： In a power drive unit having power modules (three-phase inverter circuits) connected to a control circuit board, bus bars extending from the power modules and a current sensor each installed near the bus bars and including a sensing element that detects currents outputted from the bus bars, there are provided a sensor board on which the sensing element is mounted, and lead pins each connecting the sensor board to the control circuit board and having a bowed shape whose one end is connected to the sensor board and other end once extends away from the circuit board and then turns back toward the circuit board. With this, the circuit board and current sensors can be connected through the lead pins without increasing the distance therebetween and stress produced in the lead pins can be alleviated, thereby enabling the unit to be minimized in size and utilized in a harsh service environment.
