简介：0概述目前，汽车为了降低汽油消耗，减少温室气体排放，节约社会资源，汽车轻量化正成为发展的大方向。减轻汽车自重是提高汽车的经济性，降低能耗，减少污染的重要措施之一。一般认为，汽车车体每减轻1％则可节油1％，运动部件质量每减轻1％则可节油2％。

简介：在低温下用电化学促进化学镀(EPEP)在AM60B镁合金上制备无预处理Ni-P涂层,并用SEM、AFM、EDS和XRD等技术对涂层进行表征。在阴极电流密度为4mA/cm^2、温度为50℃的条件下获得致密、均匀和中等磷含量的Ni-P涂层,其显微组织为晶态-无定型的混合态。在相同的化学镀条件下,但不施加阴极电流,合金表面形成了岛状的镍团簇镀层。在3.5%NaCl腐蚀电解液中进行电化学检测,发现EPEP镀后镁合金的耐蚀性有了明显提高。显微电镜观察进一步证实了电化学测试的结果,涂层的厚度、显微硬度、孔隙度及粘结强度均合格。

简介：据报道，一种用铂制造的燃烧预处理系统即将用于船舶行业的柴油发动机。这种技术由EcoEmissionsSystems公司发明，通过把铂基催化剂纳米溶液注入到气缸中提高催化。通过这种技术，柴油燃烧率提高，其他优点有动力提高，耗油量降低，排放物减少以及发动机寿命延长。公司称，

简介：该发明涉及一种轴类工件埋弧焊接预处理用预热工艺，包括以下步骤：首先对轴类工件进行探伤，选取没有组织缺陷的轴类工件进行表面清洗，除去轴类工件表面油污，然后对轴类工件进行喷砂处理，改善轴类工件表面组织结构，清除铁锈，然后将轴类工件放入加热炉中，将轴类工件由常温状态快速加热至200～300℃，然后在8．10h内，将轴类工件温度逐渐提升至500℃。
